5-Benzyl-2-((6-ethoxy-4-methylquinazolin-2-yl)amino)-6-methylpyrimidin-4(3H)-one CAS 500270-56-4

Description

The occurrence of 5-Benzyl-2-((6-ethoxy-4-methylquinazolin-2-yl)amino)-6-methylpyrimidin-4(3H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Benzyl-2-((6-ethoxy-4-methylquinazolin-2-yl)amino)-6-methylpyrimidin-4(3H)-one (CAS 500270-56-4), a certified reference material (molecular formula C23H23N5O2, MW 401.46 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 5-Benzyl-2-((6-ethoxy-4-methylquinazolin-2-yl)amino)-6-methylpyrimidin-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 401.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
