A purity figure describes how much of a sample is one component. It says nothing about which component. A lot can be 99% pure and be 99% something other than what the label claims, and the HPLC trace alone would look excellent.
The mass measurement closes that gap. A calculated weight from the sequence, compared against a measured weight, is a direct test of whether the molecule is the one intended.
Masses are reported in daltons, and agreement is expected within a tolerance set by the instrument. A discrepancy matching the mass of a specific residue points at a deletion; one matching 16 daltons suggests oxidation; one matching 1 dalton can indicate deamidation.
Those are diagnostic rather than decorative. A certificate that reports a measured mass is giving information that can be checked against the sequence by anyone who wants to.
Identity by mass spectrometry, purity by HPLC, water content and residual solvent reported separately. Each answers something the others cannot, which is why a complete certificate carries all of them.
Lot certificates are issued per batch here, not produced on request, and the lot number on the certificate must match the one printed on the carton.
