CATO supplies (2S)-2-((2S)-2-((2S)-2-Amino-5-((amino(sulfoamino)phosphoryl)amino)pentanamido)propanamido)-6-guanidinohexanoic acid (CAS 62249-77-8), a certified reference material (molecular formula C15H34N9O8PS, MW 531.52 g/mol) for analytical method development and quality control.
The molecular framework of (2S)-2-((2S)-2-((2S)-2-Amino-5-((amino(sulfoamino)phosphoryl)amino)pentanamido)propanamido)-6-guanidinohexanoic acid (C15H34N9O8PS) is characterized by an amide group, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
