N-(3,4-difluorophenyl)-2-((4,5-diphenyl-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 436842-77-2

Description

N-(3,4-difluorophenyl)-2-((4,5-diphenyl-4H-1,2,4-triazol-3-yl)thio)acetamide (C22H16F2N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

N-(3,4-difluorophenyl)-2-((4,5-diphenyl-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 436842-77-2) is a high-purity analytical reference standard with the molecular formula C22H16F2N4OS and a molecular weight of 422.45 g/mol.

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.

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.
