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.
3,4,5-Trifluoro-4'-(4-pentylcyclohexyl)-1,1'-biphenyl (CAS 1173199-65-9) is a high-purity analytical reference standard with the molecular formula C23H27F3 and a molecular weight of 360.46 g/mol.
3,4,5-Trifluoro-4'-(4-pentylcyclohexyl)-1,1'-biphenyl (C23H27F3) contains fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
