Chemical Structure

Sodium 4-isopropylbenzenesulfinate CAS 89520-64-9 chemical structure

Description

CATO supplies Sodium 4-isopropylbenzenesulfinate (CAS 89520-64-9), a certified reference material (molecular formula C9H11O2SNa, MW 206.23 g/mol) for analytical method development and quality control.

The molecular framework of Sodium 4-isopropylbenzenesulfinate (C9H11O2SNa) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures Sodium 4-isopropylbenzenesulfinate 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.
