(S)-1-((R)-2-((tert-Butoxycarbonyl)amino)-3-phenylpropanoyl)pyrrolidine-2-carboxylic acid CAS 138971-65-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-1-((R)-2-((tert-Butoxycarbonyl)amino)-3-phenylpropanoyl)pyrrolidine-2-carboxylic acid.

(S)-1-((R)-2-((tert-Butoxycarbonyl)amino)-3-phenylpropanoyl)pyrrolidine-2-carboxylic acid (CAS 138971-65-0), molecular formula C19H26N2O5 and molecular weight 362.42 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-1-((R)-2-((tert-Butoxycarbonyl)amino)-3-phenylpropanoyl)pyrrolidine-2-carboxylic acid (C19H26N2O5) is characterized by a flavonoid 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.

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.
