Chemical Structure

(S)-tert-Butyl 3-(2-bromo-5-(3,5-dimethylisoxazol-4-yl)phenoxy)pyrrolidine-1-carboxylate CAS 1609116-50-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-tert-Butyl 3-(2-bromo-5-(3,5-dimethylisoxazol-4-yl)phenoxy)pyrrolidine-1-carboxylate.

CATO supplies (S)-tert-Butyl 3-(2-bromo-5-(3,5-dimethylisoxazol-4-yl)phenoxy)pyrrolidine-1-carboxylate (CAS 1609116-50-8), a certified reference material (molecular formula C20H25BrN2O4, MW 437.33 g/mol) for analytical method development and quality control.

The molecular framework of (S)-tert-Butyl 3-(2-bromo-5-(3,5-dimethylisoxazol-4-yl)phenoxy)pyrrolidine-1-carboxylate (C20H25BrN2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures (S)-tert-Butyl 3-(2-bromo-5-(3,5-dimethylisoxazol-4-yl)phenoxy)pyrrolidine-1-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
