2-Hydroxy-3'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid CAS 1262011-26-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Hydroxy-3'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid.

CATO supplies 2-Hydroxy-3'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid (CAS 1262011-26-6), a certified reference material (molecular formula C17H17NO5S, MW 347.39 g/mol) for analytical method development and quality control.

2-Hydroxy-3'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid (C17H17NO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
