N-((1R,2S)-1-((R)-4,4-difluoropyrrolidin-2-yl)-1-hydroxy-3-phenylpropan-2-yl)-3-((R)-2-(4-methylthiazol-2-yl)pyrrolidine-1-carbonyl)-5-(oxazol-2-yl)benzamide CAS 1221263-99-5

Description

The molecular framework of N-((1R,2S)-1-((R)-4,4-difluoropyrrolidin-2-yl)-1-hydroxy-3-phenylpropan-2-yl)-3-((R)-2-(4-methylthiazol-2-yl)pyrrolidine-1-carbonyl)-5-(oxazol-2-yl)benzamide (C32H33F2N5O4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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).

N-((1R,2S)-1-((R)-4,4-difluoropyrrolidin-2-yl)-1-hydroxy-3-phenylpropan-2-yl)-3-((R)-2-(4-methylthiazol-2-yl)pyrrolidine-1-carbonyl)-5-(oxazol-2-yl)benzamide (CAS 1221263-99-5), molecular formula C32H33F2N5O4S and molecular weight 621.70 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
