Chemical Structure

3-Methyl-2-butenylboronic acid pinacol ester CAS 141550-13-2 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Methyl-2-butenylboronic acid pinacol ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies 3-Methyl-2-butenylboronic acid pinacol ester (CAS 141550-13-2), a certified reference material (molecular formula C11H21BO2, MW 196.09 g/mol) for analytical method development and quality control.

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.
