Chemical Structure
Description
pGlu-His-L-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-NH2 (C62H79N17O12) 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).
CATO supplies pGlu-His-L-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-NH2 (CAS CATO-C4X-186236), a certified reference material (molecular formula C62H79N17O12, MW 1254.40 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
