Chemical Structure

2-Methyl-1-propenylboronic acid pinacol ester CAS 126689-00-7 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Methyl-1-propenylboronic acid pinacol ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.07 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.

2-Methyl-1-propenylboronic acid pinacol ester (CAS 126689-00-7), molecular formula C10H19BO2 and molecular weight 182.07 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 2-Methyl-1-propenylboronic acid pinacol ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
