Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromobenzenesulfonyl chloride 2-bromobenzene sulfonyl chloride 2-bromobenzenesulfonylchloride o-bromobenzenesulfonyl chloride 2-bromophenylsulfonyl chloride 2-bromobenzene-1-sulfonyl chloride 2-bromobenzenesulphonyl chloride 2-bromo-benzenesulfonyl chloride 2-bromosulfonyl chloride 2905-25-1.

2-Bromobenzenesulfonyl chloride 2-bromobenzene sulfonyl chloride 2-bromobenzenesulfonylchloride o-bromobenzenesulfonyl chloride 2-bromophenylsulfonyl chloride 2-bromobenzene-1-sulfonyl chloride 2-bromobenzenesulphonyl chloride 2-bromo-benzenesulfonyl chloride 2-bromosulfonyl chloride 2905-25-1 (CAS 2905-25-1), molecular formula C6H10BrClO2S and molecular weight 261.56 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 2-Bromobenzenesulfonyl chloride 2-bromobenzene sulfonyl chloride 2-bromobenzenesulfonylchloride o-bromobenzenesulfonyl chloride 2-bromophenylsulfonyl chloride 2-bromobenzene-1-sulfonyl chloride 2-bromobenzenesulphonyl chloride 2-bromo-benzenesulfonyl chloride 2-bromosulfonyl chloride 2905-25-1 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-Bromobenzenesulfonyl chloride 2-bromobenzene sulfonyl chloride 2-bromobenzenesulfonylchloride o-bromobenzenesulfonyl chloride 2-bromophenylsulfonyl chloride 2-bromobenzene-1-sulfonyl chloride 2-bromobenzenesulphonyl chloride 2-bromo-benzenesulfonyl chloride 2-bromosulfonyl chloride 2905-25-1 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
