Chemical Structure
Description
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.
4,4'-Dibromo-2,2'-bis(trifluoromethyl)-1,1'-biphenyl (CAS 176714-72-0), molecular formula C14H6Br2F6 and molecular weight 448.00 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H6Br2F6, 4,4'-Dibromo-2,2'-bis(trifluoromethyl)-1,1'-biphenyl contains fluorine/bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 448.00 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.
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.
