Chemical Structure

5-Benzoyl-4-Hydroxy-2-Methoxybenzenesulfonic Acid CAS 4065-45-6 chemical structure

Description

The occurrence of 5-Benzoyl-4-Hydroxy-2-Methoxybenzenesulfonic Acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Benzoyl-4-Hydroxy-2-Methoxybenzenesulfonic Acid (CAS 4065-45-6), a certified reference material (molecular formula C14H12O6S, MW 308.31 g/mol) for analytical method development and quality control.

5-Benzoyl-4-Hydroxy-2-Methoxybenzenesulfonic Acid (C14H12O6S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
