Chemical Structure
Description
CATO supplies 2-((3-Ethyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)-N-(4-(trifluoromethoxy)phenyl)acetamide (CAS 882083-37-6), a certified reference material (molecular formula C19H16F3N3O3S, MW 423.41 g/mol) for analytical method development and quality control.
Based on its molecular formula C19H16F3N3O3S, 2-((3-Ethyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)-N-(4-(trifluoromethoxy)phenyl)acetamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 423.41 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).
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.
