4H-Cyclopenta[b]thiophene-3-carboxylic acid, 5,6-dihydro-2-isothiocyanato-, methyl ester (9CI) 588676-82-8 CAS 588676-82-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4H-Cyclopenta[b]thiophene-3-carboxylic acid, 5,6-dihydro-2-isothiocyanato-, methyl ester (9CI) 588676-82-8.

4H-Cyclopenta[b]thiophene-3-carboxylic acid, 5,6-dihydro-2-isothiocyanato-, methyl ester (9CI) 588676-82-8 (CAS 588676-82-8), molecular formula C10H9NO2S2 and molecular weight 239.31 g/mol, is a CATO reference standard with documented purity and traceability.

4H-Cyclopenta[b]thiophene-3-carboxylic acid, 5,6-dihydro-2-isothiocyanato-, methyl ester (9CI) 588676-82-8 (C10H9NO2S2) 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 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.
