Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(2-Chloro-6-nitrophenoxy)benzenesulfonyl chloride (CAS 175135-00-9), molecular formula C12H7Cl2NO5S and molecular weight 348.16 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2-Chloro-6-nitrophenoxy)benzenesulfonyl chloride (C12H7Cl2NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
As a certified reference material (CRM), 4-(2-Chloro-6-nitrophenoxy)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.
