Chemical Structure
Description
The occurrence of 4,4,5,5-Tetramethyl-2-(4-(3-(trifluoromethyl)phenoxy)phenyl)-1,3,2-dioxaborolane is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,4,5,5-Tetramethyl-2-(4-(3-(trifluoromethyl)phenoxy)phenyl)-1,3,2-dioxaborolane (CAS 2171363-95-2) is a high-purity analytical reference standard with the molecular formula C19H20BF3O3 and a molecular weight of 364.17 g/mol.
4,4,5,5-Tetramethyl-2-(4-(3-(trifluoromethyl)phenoxy)phenyl)-1,3,2-dioxaborolane (C19H20BF3O3) 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, the carboxyl group imparts weak acidity; 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.
