3-(2-(Dimethylamino)ethyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one CAS 16951-27-2

Description

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.

CATO supplies 3-(2-(Dimethylamino)ethyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one (CAS 16951-27-2), a certified reference material (molecular formula C12H15N3OS, MW 249.33 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-(2-(Dimethylamino)ethyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 249.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
