Deletions: lighter by one residue, assigned by mass. Incomplete deprotection: heavier by the group — 252 daltons for the arginine Pbf group, 56 for tert-butyl — and later eluting because the groups are hydrophobic. Oxidation: plus 16 at methionine 27, earlier eluting. Deamidation: plus 1 at asparagine 8, resolved by ion exchange better than reversed phase. Unacylated peptide: minus 96, earlier eluting, and notable because it is the native hormone.
Preparative purification removes most of these; what remains is reported.
Area percentage under one method at one wavelength. Impurities that co-elute are counted as parent; those that do not absorb are not counted; peptide content is separate. Two 98 per cent figures from different methods are not the same statement. A certificate that states the method, the wavelength and the identified impurities has told you what its number means.
For this peptide the unacylated fraction and the two degradants are the lines to read.
Because a reader comparing certificates should know what a 44-mer can contain. It describes analytics and no use of the pack.
