Chemical Structure
Description
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.
7-Hydroxy-3-(4-methoxybenzyl)chroman-4-one (CAS 103680-87-1), molecular formula C17H16O4 and molecular weight 284.31 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H16O4, 7-Hydroxy-3-(4-methoxybenzyl)chroman-4-one contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 284.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
