Chemical Structure

H-Gly-Arg-NH2 · 2 HCl CAS 24326-03-2 chemical structure

Description

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.

H-Gly-Arg-NH2 · 2 HCl (CAS 24326-03-2), molecular formula C8H18N4O2HCl and molecular weight 238.72 g/mol, is a CATO reference standard with documented purity and traceability.

H-Gly-Arg-NH2 · 2 HCl (C8H18N4O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
