Description

Compared with other compounds in its class, the molecular weight of 284.33 g/mol gives 2-Mercapto-3-(3-methoxy-phenyl)-3H-quinazolin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Mercapto-3-(3-methoxy-phenyl)-3H-quinazolin-4-one (CAS 56671-19-3), molecular formula C15H12N2O2S and molecular weight 284.33 g/mol, is a CATO reference standard with documented purity and traceability.

2-Mercapto-3-(3-methoxy-phenyl)-3H-quinazolin-4-one (C15H12N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.

CATO manufactures 2-Mercapto-3-(3-methoxy-phenyl)-3H-quinazolin-4-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.
