N-(2-ethylphenyl)-2-((4-phenyl-5-((p-tolylamino)methyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 493032-82-9) is a high-purity analytical reference standard with the molecular formula C26H27N5OS and a molecular weight of 457.59 g/mol.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, N-(2-ethylphenyl)-2-((4-phenyl-5-((p-tolylamino)methyl)-4H-1,2,4-triazol-3-yl)thio)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 457.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
