Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Bromo-5-fluorophenyl)ethanesulfonyl chloride.
2-(2-Bromo-5-fluorophenyl)ethanesulfonyl chloride (CAS 1033629-70-7), molecular formula C8H7BrClFO2S and molecular weight 301.56 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(2-Bromo-5-fluorophenyl)ethanesulfonyl chloride (C8H7BrClFO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 301.56 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures 2-(2-Bromo-5-fluorophenyl)ethanesulfonyl chloride 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.
