The occurrence of 2-(3-((2,4-Dichlorobenzyl)oxy)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(3-((2,4-Dichlorobenzyl)oxy)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2246728-07-2) is a high-purity analytical reference standard with the molecular formula C19H21BCl2O3 and a molecular weight of 379.09 g/mol.
2-(3-((2,4-Dichlorobenzyl)oxy)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C19H21BCl2O3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
