Chemical Structure

1,2-Ethynediboronic Acid Bis(pinacol) Ester CAS 1010840-17-1 chemical structure

Description

1,2-Ethynediboronic Acid Bis(pinacol) Ester (CAS 1010840-17-1) is a high-purity analytical reference standard with the molecular formula C14H24B2O4 and a molecular weight of 277.96 g/mol.

1,2-Ethynediboronic Acid Bis(pinacol) Ester (C14H24B2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

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

As a certified reference material (CRM), 1,2-Ethynediboronic Acid Bis(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.
