CATO supplies pGlu-His-L-Trp-Ser-Tyr-D-Trp-D-Leu-Arg-Pro-Gly-NH2 (CAS 321709-37-9), a certified reference material (molecular formula C64H82N18O13, MW 1311.45 g/mol) for analytical method development and quality control.
pGlu-His-L-Trp-Ser-Tyr-D-Trp-D-Leu-Arg-Pro-Gly-NH2 (C64H82N18O13) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
