Description

CATO supplies 5-[(4-Hydroxy-3-methoxy-5-methylphenyl)methylene]-1,3-dimethyl-2,4,6(1H,3H,5H)-pyrimidinetrione (CAS 860644-62-8), a certified reference material (molecular formula C15H16N2O5, MW 304.30 g/mol) for analytical method development and quality control.

Structurally, 5-[(4-Hydroxy-3-methoxy-5-methylphenyl)methylene]-1,3-dimethyl-2,4,6(1H,3H,5H)-pyrimidinetrione (C15H16N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 304.30 g/mol, it falls into the moderately-high-molecular-weight range. 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.
