5-Amino-1MQ is a small molecule rather than a peptide, so the checks are simpler but the same in kind: is it the named compound, how pure is it, how much is in the vial. For lot KB-09573, ILS Laboratories reported 99.86% HPLC purity, identity confirmed against a 5-amino-1MQ reference standard, and 52.24 mg in a 50 mg vial, fentanyl not detected.
It is sold in 50 mg vials at $43.99, with a 10-vial researcher pack, through Klow.bio. One detail to note when buying: the certificate does not state the salt form, so weights here are given for the 5-amino-1-methylquinolinium cation.
Because the molecule is a cation, it is always supplied as a salt with a counterion, commonly iodide (C10H11IN2, 286.11 g/mol). The certificate does not state the counterion, so the formula and weight shown here are for the cation itself.
The quinolinium ring is planar and strongly UV-absorbing, which suits HPLC-UV purity analysis. The positive charge is fixed on the ring nitrogen and does not depend on pH; the 5-amino group is a weak base.
5-Amino-1MQ is supplied as a lyophilized powder in 50 mg vials. It is sold through klow.bio, operated by Klow Labs LLC, where current pricing, bundle discounts and shipping options are listed. Orders ship the next business day. Same-day cutoff is 4:00 PM CT, with overnight and 2-day options at checkout.

5-Amino-1MQ Research Supply publishes lot-specific analytical documentation for its 5-Amino-1MQ research material. Each item below is published for every lot and can be checked against the laboratory record.
Every lot is tested by ILS Laboratories, an independent analytical laboratory. Published results come from the laboratory's certificate, not in-house testing.
Every lot's certificate is published as a PDF, with the chromatogram behind the purity figure, alongside a readable lot record.
The laboratory runs the sample and a reference standard of the named compound under the same HPLC conditions; identity is confirmed when the main peak elutes at the reference standard’s retention time. The method is named on every lot record, so it is clear what the result does and does not establish.
Current lots test at 99.86% by HPLC-UV, well above the ≥95% release specification, with net content measured on every lot.
Every certificate carries the laboratory's QR code. You can confirm results directly with the lab instead of taking our copy on trust.
Lots without endotoxin or microbial testing say "Not tested". Each certificate page explains what the tests do and don't establish.
5-Amino-1MQ Research Supply is built around five things: a dedicated 5-Amino-1MQ focus, a controlled supply chain, independent analytical testing, lot-level transparency and current availability. Each reason below links to the evidence. See the full quality and supply-chain process.
One compound, not a catalog of unrelated products.
Material sourced through qualified manufacturing partners.
≥95% HPLC-UV purity with identity confirmed by HPLC retention-time match against a reference standard.
Every lot tested by ILS Laboratories, with the results shown.
A public record for every lot, with dates and laboratory reference numbers.

The questions worth asking any supplier of 5-Amino-1MQ research material, why each one matters, and how 5-Amino-1MQ Research Supply answers them.
| What to check | Why it matters | 5-Amino-1MQ Research Supply |
|---|---|---|
| Independent third-party testing | Results produced by the seller can't be checked independently. | ✓ Every lot tested by ILS Laboratories |
| Lot-specific certificates | A generic certificate may not describe the vial you receive. | ✓ Each COA tied to the lot number on the vial label |
| Chromatogram available | A purity figure without the trace behind it can't be evaluated. | ✓ In the certificate PDF for every lot |
| Separate identity test | HPLC purity shows how much of the sample is the main peak, not which compound the peak is. | ✓ HPLC retention-time match on every lot |
| Measured net content | Confirms how much compound is actually in the vial. | ✓ Measured on every lot; current lots at or above label size |
| Contaminant screening | Checks for a specific contaminant the laboratory screens for. | ✓ Fentanyl screen on every current lot: not detected |
| Verifiable with the lab | Prevents altered or reused certificates. | ✓ Lab QR code on every certificate |
| Named company and contact | Accountability requires a real business you can reach. | ✓ Klow Labs LLC, Chicago; (708) 262-7687 |

Testing laboratory: ILS Laboratories. Release specification: purity ≥95% by HPLC-UV with identity confirmed by HPLC retention-time match against a reference standard. Results apply only to the lot listed. Certificates list the testing client as Klow.bio / Klow Labs LLC, the company that operates 5-Amino-1MQ Research Supply.
The current lot tested at 99.86% by HPLC-UV. Lot-to-lot comparisons will appear here as further lots are tested.
Measured net content was at or above the labeled vial size for every current lot: 52.24 mg in a 50 mg vial.
A purity figure says the sample is homogeneous; it does not say which compound the main peak is. That is answered by a separate identity test: HPLC retention-time comparison with a reference standard (HPLC-RTM).
The laboratory runs the sample and a reference standard of the named compound under the same HPLC conditions; identity is confirmed when the main peak elutes at the reference standard’s retention time. A retention-time match is consistent with the named compound under the laboratory’s method. It is not a mass measurement, which is why the method is always named next to the result.

Four methods appear on 5-Amino-1MQ certificates. Each answers a different question, and none answers every question on its own, which is why they are used together.
Reversed-phase high-performance liquid chromatography separates the sample's components by hydrophobicity, and a UV detector records each as a peak. Purity is the main peak's area as a percentage of all detected peak area.
Limits: does not identify the peak, and impurities that co-elute or absorb weakly in UV can be under-counted. More on HPLC
The laboratory runs the sample and a reference standard of 5-Amino-1MQ under the same chromatographic conditions. Identity is reported as confirmed when the sample’s main peak elutes at the reference standard’s retention time.
Limits: a retention-time match is consistent with the named compound but is not a mass or structure measurement; compounds with similar retention can co-elute. More on HPLC
The laboratory screens each lot by immunoassay at the cutoff printed on the certificate. Current lots are reported as not detected.
Limits: a negative result means below the cutoff for the sample tested; an immunoassay screens for its target only.
The laboratory quantifies the main compound in the tested vial against a standard. It is reported in milligrams next to the labeled vial size.
Limits: measured on the vial tested; other vials from the same lot are expected to be similar but are not individually measured.

5-Amino-1MQ is a small-molecule quinolinium compound. 5-Amino-1MQ Research Supply supplies it as a lyophilized powder in 50 mg vials, with an independent certificate of analysis for every lot.
5-Amino-1MQ research material is 5-Amino-1MQ supplied for laboratory research, sold by lot, with each lot's identity, purity and net content documented by an independent laboratory in a published certificate of analysis.
Because the molecule is a cation, it is always supplied as a salt with a counterion, commonly iodide (C10H11IN2, 286.11 g/mol). The certificate does not state the counterion, so the formula and weight shown here are for the cation itself.
5-Amino-1MQ is analyzed with complementary methods: HPLC-UV for purity, HPLC-RTM for identity, a quantitative measurement for net content, and, where listed, LAL endotoxin and PCR microbial testing. Results are published per lot at buy5amino.com/coa/.
Every lot is tested by ILS Laboratories, an independent third-party analytical laboratory. 5-Amino-1MQ Research Supply does not test its own material for published certificates.
Current lots report HPLC-UV purity 99.86%, against a stated release specification of ≥95%. The most recent result is 99.86% for lot KB-09573.
A 5-Amino-1MQ certificate of analysis is the testing laboratory's report for one lot: the lot number, test dates, methods and results for purity, identity and net content. 5-Amino-1MQ Research Supply publishes every lot's COA as a readable page at buy5amino.com/coa/.
Find the lot number printed on your vial label and enter it at buy5amino.com/verify/, or open that lot in the COA archive at buy5amino.com/coa/.
