Chemical Structure

(S)-2-Hydroxypropyl 4-methylbenzenesulfonate CAS 32464-98-5 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)-2-Hydroxypropyl 4-methylbenzenesulfonate.

CATO supplies (S)-2-Hydroxypropyl 4-methylbenzenesulfonate (CAS 32464-98-5), a certified reference material (molecular formula C10H14O4S, MW 230.28 g/mol) for analytical method development and quality control.

(S)-2-Hydroxypropyl 4-methylbenzenesulfonate (C10H14O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

As a certified reference material (CRM), (S)-2-Hydroxypropyl 4-methylbenzenesulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
