1,5-bis[4-(trifluoromethyl)phenyl]-1,4-pentadien-3-one CAS 103836-71-1

Description

Based on its molecular formula C19H12F6O, 1,5-bis[4-(trifluoromethyl)phenyl]-1,4-pentadien-3-one contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 370.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1,5-bis[4-(trifluoromethyl)phenyl]-1,4-pentadien-3-one (CAS 103836-71-1) is a high-purity analytical reference standard with the molecular formula C19H12F6O and a molecular weight of 370.29 g/mol.

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.
