3-[(tert-Butyldimethylsilyl)oxy]-2-chloro-6-fluorophenylboronic acid (CAS 2377611-81-7) is a high-purity analytical reference standard with the molecular formula C12H19BClFO3Si and a molecular weight of 304.63 g/mol.
The molecular framework of 3-[(tert-Butyldimethylsilyl)oxy]-2-chloro-6-fluorophenylboronic acid (C12H19BClFO3Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
