COA checks for peptide and regulated-material buyers
For licensed or FDA-registered buyers of lyophilized material: HPLC purity, identity and net content, duplicate chromatograms across synthesis batches, and no public page, ever.

File record only, because the vial spec is gated. No account, and the file is deleted after 24 hours.

Three document traps, and what the preset does
The same chromatogram on a new batch
What goes wrongTwo synthesis batches arrive with the same trace under different lot numbers.
What the preset doesEach accepted COA is fingerprinted and compared. A match is a high signal, and the lot is blocked until a person clears it with a note.
registry matchA short vial
What goes wrong8.1 mg measured against a 10 mg label is 81%, below the 90% floor, while the cover page says the lot passed.
What the preset doesThe content is worked out against your label, and the lot fails on it.
NET_CONTENT_OUT_OF_TOLERANCEA research-use-only statement
What goes wrongThe COA carries “research use only” in small print.
What the preset doesIt is a blocker in 503A mode, a warning on a custom spec, and it always bars a public page.
RUO_NOT_ELIGIBLE
The preset: Standard Lyophilized Vial ≥98% HPLC + 90–110% Net Content
- Purity
- At least 98% area, by HPLC only. Any other method is a finding.
- Identity
- Must conform. To require mass spec, set the allowed methods on the spec; another method is then a finding.
- Net content
- 90% to 110% of your labelled mg per vial.
- Access
- Opens only after a license or FDA-registration check. Set by the server, never by a form.
- Public pages
- Never for this category or for a research-use-only COA. A database trigger refuses them for every writer.
What it does not do
- This is for licensed or FDA-registered buyers checking inbound material. Selling products for human use on a research-use-only COA breaks our acceptable-use policy.
- The free check does not run the vial spec, because that spec needs the license check first. It reads the file’s own record, with no AI read and nothing entered in the registry.
- Duplicate chromatograms are compared in a workspace, never on the free check, so that nobody can probe the registry.
