Chemical Structure

3-(4-Chloro-benzyl)-2-mercapto-3H-quinazolin-4-one CAS 35976-99-9 chemical structure

Description

The occurrence of 3-(4-Chloro-benzyl)-2-mercapto-3H-quinazolin-4-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(4-Chloro-benzyl)-2-mercapto-3H-quinazolin-4-one (CAS 35976-99-9), a certified reference material (molecular formula C15H11ClN2OS, MW 302.78 g/mol) for analytical method development and quality control.

3-(4-Chloro-benzyl)-2-mercapto-3H-quinazolin-4-one (C15H11ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 3-(4-Chloro-benzyl)-2-mercapto-3H-quinazolin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
