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 2-Hydroxy-3-phenyl-4H-pyrido[1,2-a]pyrimidin-4-one 4333AF 95533-95-2 C14H10N2O2 (CAS 95533-95-2), a certified reference material (molecular formula C14H10N2O2, MW 238.24 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-Hydroxy-3-phenyl-4H-pyrido[1,2-a]pyrimidin-4-one 4333AF 95533-95-2 C14H10N2O2 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
