Chemical Structure
Description
The occurrence of (S)-N-((S)-1-(((S)-1-Chloro-6-guanidino-2-oxohexan-3-yl)amino)-1-oxo-3-phenylpropan-2-yl)pyrrolidine-2-carboxamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-N-((S)-1-(((S)-1-Chloro-6-guanidino-2-oxohexan-3-yl)amino)-1-oxo-3-phenylpropan-2-yl)pyrrolidine-2-carboxamide (CAS 65149-23-7) is a high-purity analytical reference standard with the molecular formula C21H31ClN6O3 and a molecular weight of 450.96 g/mol.
The molecular framework of (S)-N-((S)-1-(((S)-1-Chloro-6-guanidino-2-oxohexan-3-yl)amino)-1-oxo-3-phenylpropan-2-yl)pyrrolidine-2-carboxamide (C21H31ClN6O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
