(3R,4S)-rel-1-(tert-Butoxycarbonyl)-4-(3-(trifluoromethoxy)phenyl)pyrrolidine-3-carboxylic acid CAS 1255934-39-4 chemical structure

Description

The occurrence of (3R,4S)-rel-1-(tert-Butoxycarbonyl)-4-(3-(trifluoromethoxy)phenyl)pyrrolidine-3-carboxylic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (3R,4S)-rel-1-(tert-Butoxycarbonyl)-4-(3-(trifluoromethoxy)phenyl)pyrrolidine-3-carboxylic acid (CAS 1255934-39-4), a certified reference material (molecular formula C17H20F3NO5, MW 375.34 g/mol) for analytical method development and quality control.

The molecular framework of (3R,4S)-rel-1-(tert-Butoxycarbonyl)-4-(3-(trifluoromethoxy)phenyl)pyrrolidine-3-carboxylic acid (C17H20F3NO5) is characterized by a flavonoid core, an amide 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).

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.
