1-(5,7-Dihydroxy-2,2-dimethyl-2H-chromen-6-yl)ethanone (CAS 31380-13-9), molecular formula C13H14O4 and molecular weight 234.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5,7-Dihydroxy-2,2-dimethyl-2H-chromen-6-yl)ethanone (C13H14O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
