Chemical Structure

3-Methyl-2-(p-tolyl)quinazolin-4(3H)-one CAS 74375-16-9 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.

CATO supplies 3-Methyl-2-(p-tolyl)quinazolin-4(3H)-one (CAS 74375-16-9), a certified reference material (molecular formula C16H14N2O, MW 250.30 g/mol) for analytical method development and quality control.

The molecular framework of 3-Methyl-2-(p-tolyl)quinazolin-4(3H)-one (C16H14N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
