2,4-Difluoro-5-methyl-3-(2-methylpropoxy)phenylboronic acid CAS 2096339-91-0

Description

The occurrence of 2,4-Difluoro-5-methyl-3-(2-methylpropoxy)phenylboronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,4-Difluoro-5-methyl-3-(2-methylpropoxy)phenylboronic acid (CAS 2096339-91-0), a certified reference material (molecular formula C11H15BF2O3, MW 244.04 g/mol) for analytical method development and quality control.

2,4-Difluoro-5-methyl-3-(2-methylpropoxy)phenylboronic acid (C11H15BF2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
