How to read these results
HPLC purity is the share of the peptide material that is the target sequence. The mass spectrometry result confirms it is the right molecule. Measured content is compared against the label claim, and endotoxin is reported only where the laboratory tested for it.
Compound
A cyclic α-MSH analogue studied as a non-selective melanocortin receptor agonist.
