Documentation policy
Certificates of Analysis are released after purchase.
Every lot we ship is tested by an accredited third-party laboratory, and every customer is entitled to the certificate for the lot they received. We do not publish a browsable COA library. Instead, we release your certificate to you, tied to your order and your lot number — free, on request, for as long as we keep the record.
Why we hold certificates back
This is a customer-protection and industry-integrity measure, not a way to withhold information.
A COA only means something when it matches your vial
A certificate is a lot-specific document, not a marketing asset. Publishing a browsable library invites people to pair a document with material it was never issued for. Releasing your COA after purchase guarantees the lot number on the paperwork is the lot number in your hands.
Public COA libraries get scraped and reused
Signed certificates carrying our lab's letterhead and batch data are routinely copied by unrelated sellers to imply testing that never happened. Restricting release protects buyers from counterfeit documentation and protects the analytical labs whose names appear on it.
Certificates are controlled records, not advertising
Analytical documents describe a research material's identity and purity. Presented next to a purchase button, they read as product performance claims. Keeping them out of the shopping path keeps our storefront strictly research-use-only in tone and substance.
Traceability requires a named recipient
Because each release is tied to an order, we can reach you directly if a lot is ever re-tested, amended, or withdrawn. Anonymous downloads make that impossible.
The policy, in full
- Who can request
- Any customer with a completed order, for any lot contained in that order. Institutional buyers may also request pre-purchase documentation in writing for procurement review.
- What you receive
- The full third-party Certificate of Analysis for your lot: identity, HPLC purity, mass spectrometry confirmation, water content, acetate content, endotoxin and sterility results where applicable, with methods, specifications, test dates, and the releasing signature.
- Turnaround
- One business day or less from a verified request. There is no fee, and there is no limit on how many times you may re-request a lot you purchased.
- Retention
- Batch records and certificates are retained for a minimum of five years from the manufacture date, so a COA can be reissued long after a lot is exhausted.
- Redistribution
- Certificates are released for your own verification and recordkeeping. Please do not republish them or present them as documentation for material sourced elsewhere.
- If a result looks wrong
- Stop using the material and contact us before anything else. We will pull the retained sample, re-test if warranted, and issue a corrected or withdrawn certificate to every customer who received the lot.
All materials are sold for in-vitro laboratory research use only, and are not for human or animal consumption or for diagnostic or therapeutic use. Analytical documentation describes the identity and purity of a research chemical; it is not evidence of safety, efficacy, or fitness for any use in people or animals.
