Chemical Structure
Description
As a certified reference material (CRM), 4-Fluoro-3-(1H-tetrazol-5-yl)benzenesulfonyl chloride 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.
4-Fluoro-3-(1H-tetrazol-5-yl)benzenesulfonyl chloride (CAS 926222-53-9) is a high-purity analytical reference standard with the molecular formula C7H4ClFN4O2S and a molecular weight of 262.65 g/mol.
4-Fluoro-3-(1H-tetrazol-5-yl)benzenesulfonyl chloride (C7H4ClFN4O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
