Chemical Structure

3-(3-Chloro-2-methylphenyl)-2-sulfanyl-3,4-dihydroquinazolin-4-one CAS 81066-84-4 chemical structure

Description

CATO supplies 3-(3-Chloro-2-methylphenyl)-2-sulfanyl-3,4-dihydroquinazolin-4-one (CAS 81066-84-4), a certified reference material (molecular formula C15H11ClN2OS, MW 302.78 g/mol) for analytical method development and quality control.

3-(3-Chloro-2-methylphenyl)-2-sulfanyl-3,4-dihydroquinazolin-4-one (C15H11ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
