Chemical Structure
Description
The occurrence of Ethyl 4-cyano-5-(2-((3-cyano-5,6,7,8,9,10-hexahydrocycloocta[b]pyridin-2-yl)thio)acetamido)-3-methylthiophene-2-carboxylate is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 4-cyano-5-(2-((3-cyano-5,6,7,8,9,10-hexahydrocycloocta[b]pyridin-2-yl)thio)acetamido)-3-methylthiophene-2-carboxylate (CAS 488108-33-4), molecular formula C23H24N4O3S2 and molecular weight 468.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 4-cyano-5-(2-((3-cyano-5,6,7,8,9,10-hexahydrocycloocta[b]pyridin-2-yl)thio)acetamido)-3-methylthiophene-2-carboxylate (C23H24N4O3S2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
