The occurrence of 2,4-Xylenesulfonic Acid Monohydrate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,4-Xylenesulfonic Acid Monohydrate (CAS 58811-92-0), a certified reference material (molecular formula C8H10O3SH2O, MW 204.24 g/mol) for analytical method development and quality control.
2,4-Xylenesulfonic Acid Monohydrate (C8H10O3SH2O) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
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), 2,4-Xylenesulfonic Acid Monohydrate 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.
