Chemical Structure
Description
N-Methyl-2-(3-(phenylthio)propanamido)-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carboxamide (CAS 868965-71-3) is a high-purity analytical reference standard with the molecular formula C18H20N2O2S2 and a molecular weight of 360.49 g/mol.
N-Methyl-2-(3-(phenylthio)propanamido)-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carboxamide (C18H20N2O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
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), N-Methyl-2-(3-(phenylthio)propanamido)-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carboxamide 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.
