2,2-Bis(4-hydroxyphenyl)propanoic acid CAS 92549-67-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2-Bis(4-hydroxyphenyl)propanoic acid.

CATO supplies 2,2-Bis(4-hydroxyphenyl)propanoic acid (CAS 92549-67-2), a certified reference material (molecular formula C15H14O4, MW 258.27 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2,2-Bis(4-hydroxyphenyl)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
