Chemical Structure
Description
The occurrence of N-(4-chlorobenzyl)-2-((3-cyano-4-(trifluoromethyl)-6,7-dihydro-5H-cyclopenta[b]pyridin-2-yl)thio)acetamide is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(4-chlorobenzyl)-2-((3-cyano-4-(trifluoromethyl)-6,7-dihydro-5H-cyclopenta[b]pyridin-2-yl)thio)acetamide (CAS 626221-53-2) is a high-purity analytical reference standard with the molecular formula C19H15ClF3N3OS and a molecular weight of 425.86 g/mol.
N-(4-chlorobenzyl)-2-((3-cyano-4-(trifluoromethyl)-6,7-dihydro-5H-cyclopenta[b]pyridin-2-yl)thio)acetamide (C19H15ClF3N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
