7-Chloro-2-(((2-chlorophenyl)thio)methyl)-3-(3,5-dimethylphenyl)quinazolin-4(3H)-one CAS 338966-08-8

Description

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 7-Chloro-2-(((2-chlorophenyl)thio)methyl)-3-(3,5-dimethylphenyl)quinazolin-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 441.37 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.

CATO supplies 7-Chloro-2-(((2-chlorophenyl)thio)methyl)-3-(3,5-dimethylphenyl)quinazolin-4(3H)-one (CAS 338966-08-8), a certified reference material (molecular formula C23H18Cl2N2OS, MW 441.37 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.
