Chemical Structure

2,4,6-Trimethylbenzenesulfonic acid CAS 3453-83-6 chemical structure

Description

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2,4,6-Trimethylbenzenesulfonic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2,4,6-Trimethylbenzenesulfonic acid (CAS 3453-83-6) is a high-purity analytical reference standard with the molecular formula C9H12O3S and a molecular weight of 200.25 g/mol.

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 2,4,6-Trimethylbenzenesulfonic acid 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.
