L-Tryptophyl-L-arginyl-L-glutaminyl-L-alanyl-L-alanyl-L-phenylalanyl-L-valyl-L-a-aspartyl-L-seryl-L-tyrosine TFA Salt CAS 955091-53-9

Description

L-Tryptophyl-L-arginyl-L-glutaminyl-L-alanyl-L-alanyl-L-phenylalanyl-L-valyl-L-a-aspartyl-L-seryl-L-tyrosine TFA Salt (C58H79N15O16) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
