Chemical Structure

3,6-dimethyl-2-sulfanyl-3,4-dihydroquinazolin-4-one CAS 80195-31-9 chemical structure

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.

3,6-dimethyl-2-sulfanyl-3,4-dihydroquinazolin-4-one (CAS 80195-31-9), molecular formula C10H18N2OS and molecular weight 214.33 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H18N2OS, 3,6-dimethyl-2-sulfanyl-3,4-dihydroquinazolin-4-one contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
