Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1233505-75-3 2,3-Dichlorobenzenesulfinic acid sodium salt MFCD11618039 (CAS 1233505-75-3), a certified reference material (molecular formula C6H3Cl2O2SNa, MW 233.04 g/mol) for analytical method development and quality control.
1233505-75-3 2,3-Dichlorobenzenesulfinic acid sodium salt MFCD11618039 (C6H3Cl2O2SNa) contains a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 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).
As a certified reference material (CRM), 1233505-75-3 2,3-Dichlorobenzenesulfinic acid sodium salt MFCD11618039 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.
