2-{[3-cyano-4-(trifluoromethyl)-5H,6H,7H-cyclopenta[b]pyridin-2-yl]sulfanyl}-N-[3-(trifluoromethyl)phenyl]acetamide CAS 626227-18-7

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

2-{[3-cyano-4-(trifluoromethyl)-5H,6H,7H-cyclopenta[b]pyridin-2-yl]sulfanyl}-N-[3-(trifluoromethyl)phenyl]acetamide (CAS 626227-18-7), molecular formula C19H13F6N3OS and molecular weight 445.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-{[3-cyano-4-(trifluoromethyl)-5H,6H,7H-cyclopenta[b]pyridin-2-yl]sulfanyl}-N-[3-(trifluoromethyl)phenyl]acetamide (C19H13F6N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

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.
