2-((4-Ethyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-fluorophenyl)acetamide CAS 557065-83-5

Description

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.

CATO supplies 2-((4-Ethyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-fluorophenyl)acetamide (CAS 557065-83-5), a certified reference material (molecular formula C17H16FN5OS, MW 357.41 g/mol) for analytical method development and quality control.

Structurally, 2-((4-Ethyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(3-fluorophenyl)acetamide (C17H16FN5OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 357.41 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
