1,1,2,2-Tetrafluoro-1,2-bis(3-(trifluoromethyl)phenyl)ethane CAS 287172-67-2

Description

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.

CATO supplies 1,1,2,2-Tetrafluoro-1,2-bis(3-(trifluoromethyl)phenyl)ethane (CAS 287172-67-2), a certified reference material (molecular formula C16H8F10, MW 390.22 g/mol) for analytical method development and quality control.

Owing to fluorine substitution, a polycyclic aromatic system, 1,1,2,2-Tetrafluoro-1,2-bis(3-(trifluoromethyl)phenyl)ethane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
