Chemical Structure

4-Ethoxycarbonylphenylboronic acid pinacol ester CAS 195062-62-5 chemical structure

Description

Structurally, 4-Ethoxycarbonylphenylboronic acid pinacol ester (C15H27BO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 282.18 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4-Ethoxycarbonylphenylboronic acid pinacol ester (CAS 195062-62-5), molecular formula C15H27BO4 and molecular weight 282.18 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
