Description
CATO manufactures 3-Bromo-5-chloro-2-fluorobenzenethiol 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.
3-Bromo-5-chloro-2-fluorobenzenethiol (CAS 1823495-98-2) is a high-purity analytical reference standard with the molecular formula C6H3BrClFS and a molecular weight of 241.51 g/mol.
Owing to sulfur-containing functionality, fluorine/chlorine/bromine substitution, an aromatic ring system, 3-Bromo-5-chloro-2-fluorobenzenethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 241.51 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
