CATO supplies trans,trans-4'-Ethyl-4-(3,4,5-trifluorophenyl)bicyclohexyl (CAS 139215-80-8), a certified reference material (molecular formula C20H27F3, MW 324.42 g/mol) for analytical method development and quality control.
trans,trans-4'-Ethyl-4-(3,4,5-trifluorophenyl)bicyclohexyl (C20H27F3) contains fluorine substitution, an aromatic ring 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. 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.
