Chemical Structure

But-1-en-2-ylboronic acid CAS 682748-18-1 chemical structure

Description

The molecular framework of But-1-en-2-ylboronic acid (C4H9BO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

But-1-en-2-ylboronic acid (CAS 682748-18-1) is a high-purity analytical reference standard with the molecular formula C4H9BO2 and a molecular weight of 99.92 g/mol.

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), But-1-en-2-ylboronic acid 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.
