Chemical Structure

Ethyl 2-(2-((3-cyano-4-(thiophen-2-yl)-6,7-dihydro-5H-cyclopenta[b]pyridin-2-yl)thio)acetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate CAS 625369-18-8 chemical structure

Description

The molecular framework of Ethyl 2-(2-((3-cyano-4-(thiophen-2-yl)-6,7-dihydro-5H-cyclopenta[b]pyridin-2-yl)thio)acetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (C26H25N3O3S3) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
