Every lot, independently analyzed

Everything on this page describes how we document what we sell. None of it is a statement about what any compound does. Our job is provenance and analytics; interpretation of the science is yours.

The one-page version

1. Each production lot is tested by an independent third-party laboratory.
2. That lot's Certificate of Analysis is published to the product page and reachable through lot lookup.
3. You can look up any lot by the number on the vial and read the same report we hold.
4. When a lot sells out, the next lot ships with its own new COA. Reports are not reused across lots.

What a Certificate of Analysis reports

Identity (confirmation the material matches the intended sequence, by the stated method), purity (proportion of target compound, with method noted), mass / net quantity per vial, the lot number, and the testing laboratory and date. A COA describes the sample — not any use, effect, or suitability for any purpose beyond research characterization.

The methods we report

High-Performance Liquid Chromatography (HPLC) — purity, by separating components of the sample. Mass Spectrometry (MS) — identity, by measuring molecular mass against the expected value. The specific methods, parameters, and acceptance criteria for a given lot are stated on that lot's COA. Where a method or parameter is not yet confirmed, the field says so plainly instead of carrying a guessed value.

Laboratory & accreditation status

Incoming analysis is performed by our contracted analytical laboratory. That laboratory is not ISO/IEC 17025 accredited, and it does not run the full panel — endotoxin, heavy metals, and bioburden require a second laboratory, which is not yet engaged. We state this plainly rather than imply an accreditation we do not hold. Those three assays appear on every certificate marked pending, and they stay pending until a second laboratory reports them.

How lot lookup works

Find the lot number on the vial label, enter it in the Lot Lookup field (site header, homepage, footer, and each product page), and read the COA on file for that exact lot. If a lot number returns no result, do not use the material as identified — contact us so we can verify the label against our records.

What we will not do

• We will not reuse one lot's COA to represent a different lot.
• We will not publish a purity or mass figure we cannot tie to a test report.
• We will not state a method, CAS number, molecular weight, or specification we have not confirmed — an unconfirmed field reads Reported on the lot certificate and stays empty until the report fills it.
• We will not characterize any result as a benefit, outcome, or reason to expect anything from the compound.
