2-((4-Ethyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-fluorophenyl)acetamide CAS 557065-87-9

Description

The occurrence of 2-((4-Ethyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-fluorophenyl)acetamide is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((4-Ethyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-fluorophenyl)acetamide (CAS 557065-87-9), molecular formula C17H16FN5OS and molecular weight 357.41 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 2-((4-Ethyl-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-fluorophenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
