Ethyl 4-methylbenzenesulfinate CAS 1858-86-2 chemical structure

Description

CATO manufactures Ethyl 4-methylbenzenesulfinate 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.

Ethyl 4-methylbenzenesulfinate (CAS 1858-86-2) is a high-purity analytical reference standard with the molecular formula C9H12O2S and a molecular weight of 184.26 g/mol.

Ethyl 4-methylbenzenesulfinate (C9H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
