Based on its molecular formula C17H14N4OS, 4-[(4-methylphenyl)methyl]-1-sulfanyl-4h,5h-[1,2,4]triazolo[4,3-a]quinazolin-5-one contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 322.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 4-[(4-methylphenyl)methyl]-1-sulfanyl-4h,5h-[1,2,4]triazolo[4,3-a]quinazolin-5-one (CAS 722465-51-2), a certified reference material (molecular formula C17H14N4OS, MW 322.38 g/mol) for analytical method development and quality control.
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.
