Chemical Structure
Description
CATO supplies 1-(6-Hydroxy-3-methoxy-2,4-dimethylphenyl)-7-methoxynaphthalen-2-ol (CAS 1832513-67-3), a certified reference material (molecular formula C20H20O4, MW 324.37 g/mol) for analytical method development and quality control.
The molecular framework of 1-(6-Hydroxy-3-methoxy-2,4-dimethylphenyl)-7-methoxynaphthalen-2-ol (C20H20O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
