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.
CATO supplies (S)-2-((S)-1-(2-((S)-2,6-Diaminohexanamido)acetyl)pyrrolidine-2-carboxamido)-4-methylpentanoic acid (CAS 185312-00-9), a certified reference material (molecular formula C19H35N5O5, MW 413.51 g/mol) for analytical method development and quality control.
The molecular framework of (S)-2-((S)-1-(2-((S)-2,6-Diaminohexanamido)acetyl)pyrrolidine-2-carboxamido)-4-methylpentanoic acid (C19H35N5O5) is characterized by a steroid core, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
