1-(3',5'-Dimethyl-[1,1'-biphenyl]-4-yl)-2,2,2-trifluoroethanone CAS 1443350-64-8

Description

Compared with other compounds in its class, the molecular weight of 278.27 g/mol gives 1-(3',5'-Dimethyl-[1,1'-biphenyl]-4-yl)-2,2,2-trifluoroethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(3',5'-Dimethyl-[1,1'-biphenyl]-4-yl)-2,2,2-trifluoroethanone (CAS 1443350-64-8), molecular formula C16H13F3O and molecular weight 278.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(3',5'-Dimethyl-[1,1'-biphenyl]-4-yl)-2,2,2-trifluoroethanone (C16H13F3O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
