Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 456.23 g/mol gives Bis(3,5-bis(trifluoromethyl)phenyl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bis(3,5-bis(trifluoromethyl)phenyl)methanol (CAS 87901-76-6) is a high-purity analytical reference standard with the molecular formula C17H8F12O and a molecular weight of 456.23 g/mol.
Bis(3,5-bis(trifluoromethyl)phenyl)methanol (C17H8F12O) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. 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.
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.
