Chemical Structure

2,5-Dimethylbenzenesulfonic acid hydrate CAS 273200-04-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 204.24 g/mol gives 2,5-Dimethylbenzenesulfonic acid hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,5-Dimethylbenzenesulfonic acid hydrate (CAS 273200-04-7), a certified reference material (molecular formula C8H10O3SH2O, MW 204.24 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2,5-Dimethylbenzenesulfonic acid hydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 2,5-Dimethylbenzenesulfonic acid hydrate 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.
