Chemical Structure
Description
2-((4-Methoxybenzyl)thio)-3-methylquinazolin-4(3H)-one (CAS 90852-47-4) is a high-purity analytical reference standard with the molecular formula C17H16N2O2S and a molecular weight of 312.39 g/mol.
The molecular framework of 2-((4-Methoxybenzyl)thio)-3-methylquinazolin-4(3H)-one (C17H16N2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-((4-Methoxybenzyl)thio)-3-methylquinazolin-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.
