CATO supplies 257610-91-6 8530AD C13H15NO2S2 Ethyl 2-isothiocyanato-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate (CAS 257610-91-6), a certified reference material (molecular formula C13H15NO2S2, MW 281.39 g/mol) for analytical method development and quality control.
257610-91-6 8530AD C13H15NO2S2 Ethyl 2-isothiocyanato-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate (C13H15NO2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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), 257610-91-6 8530AD C13H15NO2S2 Ethyl 2-isothiocyanato-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate 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.
