Description
CATO supplies 2-Cyano-3-[5-[4-(diphenylamino)phenyl]thieno[3,2-b]thien-2-yl]-2-propenoic acid (CAS 1092363-69-3), a certified reference material (molecular formula C28H18N2O2S2, MW 478.58 g/mol) for analytical method development and quality control.
2-Cyano-3-[5-[4-(diphenylamino)phenyl]thieno[3,2-b]thien-2-yl]-2-propenoic acid (C28H18N2O2S2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 2-Cyano-3-[5-[4-(diphenylamino)phenyl]thieno[3,2-b]thien-2-yl]-2-propenoic 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.
