What every certificate covers
Identity
Mass spectrometry [M+H]+ confirms molecular weight matches theoretical value.
Purity
Reverse-phase HPLC with UV detection quantifies peptide content and impurities.
Endotoxin
Two replicate LAL endotoxin screening; documented pass/fail.
Appearance
Visual and quantitative verification of lyophilized product weight.
Verification FAQ
Where is the lot number on my vial?
The lot number is printed on the vial label directly beneath the compound name. It matches the Lot field on the certificate for that batch.
What does the search code mean?
The search code is built from the first four characters of the company name plus the accession number — for this catalog, Omni plus the accession. Codes are not case-sensitive.
Why do some lots show N/A?
Older certificates issued before lot-level tracking was introduced do not carry a lot identifier. The accession number still uniquely identifies the tested sample.
How often are new certificates published?
New certificate records appear in the public archive when batch documentation is available in the site dataset.
