2-((4-Ethyl-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-(trifluoromethyl)phenyl)acetamide (CAS 618414-71-4), molecular formula C18H16F3N5OS and molecular weight 407.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((4-Ethyl-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-(trifluoromethyl)phenyl)acetamide (C18H16F3N5OS) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 2-((4-Ethyl-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-(trifluoromethyl)phenyl)acetamide 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.
