Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Bromo-2,4-dichlorobenzenethiol (CAS 1349718-23-5), a certified reference material (molecular formula C6H3BrCl2S, MW 257.96 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system, 3-Bromo-2,4-dichlorobenzenethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.96 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).
CATO manufactures 3-Bromo-2,4-dichlorobenzenethiol 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.
