Chemical Structure
Description
2-((4-Allyl-5-(4-fluorophenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-cyano-3-methylbutan-2-yl)propanamide (C20H24FN5OS) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-((4-Allyl-5-(4-fluorophenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-cyano-3-methylbutan-2-yl)propanamide (CAS 851281-20-4) is a high-purity analytical reference standard with the molecular formula C20H24FN5OS and a molecular weight of 401.50 g/mol.
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.
