Chemical Structure

3,4-Dihydroquinazoline-2(1H)-thione CAS 22820-08-2 chemical structure

Description

3,4-Dihydroquinazoline-2(1H)-thione (C8H8N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 3,4-Dihydroquinazoline-2(1H)-thione (CAS 22820-08-2), a certified reference material (molecular formula C8H8N2S, MW 164.23 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.
