2-Methyl-3-(3-methylpyridin-2-yl)quinazolin-4(3H)-one CAS 3214-64-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methyl-3-(3-methylpyridin-2-yl)quinazolin-4(3H)-one.

2-Methyl-3-(3-methylpyridin-2-yl)quinazolin-4(3H)-one (CAS 3214-64-0) is a high-purity analytical reference standard with the molecular formula C15H13N3O and a molecular weight of 251.28 g/mol.

2-Methyl-3-(3-methylpyridin-2-yl)quinazolin-4(3H)-one (C15H13N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.

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.
