Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(1,1-dioxothian-3-yl)prop-2-ynoic acid (CAS 1894891-77-0), molecular formula C8H10O4S and molecular weight 202.23 g/mol, is a CATO reference standard with documented purity and traceability.
3-(1,1-dioxothian-3-yl)prop-2-ynoic acid (C8H10O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
As a certified reference material (CRM), 3-(1,1-dioxothian-3-yl)prop-2-ynoic acid 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.
