Chemical Structure

S-methyl benzothioate CAS 5925-68-8 chemical structure

Description

CATO supplies S-methyl benzothioate (CAS 5925-68-8), a certified reference material (molecular formula C8H8OS, MW 152.21 g/mol) for analytical method development and quality control.

S-methyl benzothioate (C8H8OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
