3-(2-Chlorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1h)-one CAS 65141-60-8 chemical structure

Description

The occurrence of 3-(2-Chlorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1h)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(2-Chlorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1h)-one (CAS 65141-60-8), a certified reference material (molecular formula C14H9ClN2OS, MW 288.75 g/mol) for analytical method development and quality control.

Structurally, 3-(2-Chlorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1h)-one (C14H9ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 288.75 g/mol, it falls into the medium-molecular-weight range. 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.
