(E)-3-(4-Fluorobenzylidene)chroman-4-one CAS 948307-89-9

Description

Compared with other compounds in its class, the molecular weight of 254.26 g/mol gives (E)-3-(4-Fluorobenzylidene)chroman-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-3-(4-Fluorobenzylidene)chroman-4-one (CAS 948307-89-9), molecular formula C16H11FO2 and molecular weight 254.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, (E)-3-(4-Fluorobenzylidene)chroman-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
