3-(Methoxycarbonyl)-4-methylphenylboronic Acid Pinacol Ester CAS 478375-39-2

Description

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.

3-(Methoxycarbonyl)-4-methylphenylboronic Acid Pinacol Ester (CAS 478375-39-2) is a high-purity analytical reference standard with the molecular formula C15H21BO4 and a molecular weight of 276.14 g/mol.

3-(Methoxycarbonyl)-4-methylphenylboronic Acid Pinacol Ester (C15H21BO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
