Chemical Structure
Description
The occurrence of O-(4-bromo-2-chlorophenyl)-O,S- diethyl phosphorothioate is closely related to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
O-(4-bromo-2-chlorophenyl)-O,S- diethyl phosphorothioate (CAS 71093-61-3) is a high-purity analytical reference standard with the molecular formula C10H13BrClO3PS and a molecular weight of 359.60 g/mol.
Owing to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, O-(4-bromo-2-chlorophenyl)-O,S- diethyl phosphorothioate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.60 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures O-(4-bromo-2-chlorophenyl)-O,S- diethyl phosphorothioate 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.
