3-Methyl-1H-benzo[f]chromen-1-one (CAS 5891-82-7) is a high-purity analytical reference standard with the molecular formula C14H10O2 and a molecular weight of 210.23 g/mol.
The molecular framework of 3-Methyl-1H-benzo[f]chromen-1-one (C14H10O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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.
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.
