CATO supplies 2-(Benzylsulfanyl)-1,1-bis(4-fluorophenyl)ethan-1-ol (CAS 303152-09-2), a certified reference material (molecular formula C21H18F2OS, MW 356.43 g/mol) for analytical method development and quality control.
2-(Benzylsulfanyl)-1,1-bis(4-fluorophenyl)ethan-1-ol (C21H18F2OS) contains a steroid core, sulfur-containing functionality, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
