Chemical Structure
Description
926044-96-4 Methyl 2-isocyanato-4,5-dimethylthiophene-3-carboxylate MFCD22056668 (CAS 926044-96-4), molecular formula C9H9NO3S and molecular weight 211.24 g/mol, is a CATO reference standard with documented purity and traceability.
926044-96-4 Methyl 2-isocyanato-4,5-dimethylthiophene-3-carboxylate MFCD22056668 (C9H9NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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), 926044-96-4 Methyl 2-isocyanato-4,5-dimethylthiophene-3-carboxylate MFCD22056668 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.
