Chemical Structure

3-Methyl-2-((4-methylbenzyl)thio)quinazolin-4(3H)-one CAS 22312-45-4 chemical structure

Description

3-Methyl-2-((4-methylbenzyl)thio)quinazolin-4(3H)-one (CAS 22312-45-4) is a high-purity analytical reference standard with the molecular formula C17H16N2OS and a molecular weight of 296.39 g/mol.

Structurally, 3-Methyl-2-((4-methylbenzyl)thio)quinazolin-4(3H)-one (C17H16N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 296.39 g/mol, it falls into the medium-molecular-weight range. 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.

CATO manufactures 3-Methyl-2-((4-methylbenzyl)thio)quinazolin-4(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
