Methyl 2,6-bis((4,6-dimethoxypyrimidin-2-yl)oxy)benzoate CAS 142966-13-0 chemical structure

Description

The occurrence of Methyl 2,6-bis((4,6-dimethoxypyrimidin-2-yl)oxy)benzoate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 2,6-bis((4,6-dimethoxypyrimidin-2-yl)oxy)benzoate (CAS 142966-13-0), molecular formula C20H20N4O8 and molecular weight 444.39 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H20N4O8, Methyl 2,6-bis((4,6-dimethoxypyrimidin-2-yl)oxy)benzoate contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 444.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
