Chemical Structure
Description
The occurrence of 4-((4-Chlorophenyl)thio)-5,8-difluorochroman-3-ol is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-((4-Chlorophenyl)thio)-5,8-difluorochroman-3-ol (CAS 944950-69-0) is a high-purity analytical reference standard with the molecular formula C15H11ClF2O2S and a molecular weight of 328.76 g/mol.
4-((4-Chlorophenyl)thio)-5,8-difluorochroman-3-ol (C15H11ClF2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).
