1-(3,4-Bis(trifluoromethyl)phenyl)ethanone CAS 129604-25-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3,4-Bis(trifluoromethyl)phenyl)ethanone.

1-(3,4-Bis(trifluoromethyl)phenyl)ethanone (CAS 129604-25-7), molecular formula C10H6F6O and molecular weight 256.14 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H6F6O, 1-(3,4-Bis(trifluoromethyl)phenyl)ethanone contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
