Chemical Structure
Description
3-(4-Methoxyphenyl)-1-(2,4,6-trihydroxyphenyl)propan-1-one (CAS 76172-68-4), molecular formula C16H16O5 and molecular weight 288.30 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Methoxyphenyl)-1-(2,4,6-trihydroxyphenyl)propan-1-one (C16H16O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
