Chemical Structure

3-(3-Fluorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one CAS 65141-59-5 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 3-(3-Fluorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 272.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies 3-(3-Fluorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one (CAS 65141-59-5), a certified reference material (molecular formula C14H9FN2OS, MW 272.30 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.
