Chemical Structure

3,4-Dihydro-2<I>H</I>-pyran-6-boronic acid pinacol ester CAS 1025707-93-0 chemical structure

Description

As a certified reference material (CRM), 3,4-Dihydro-2<I>H</I>-pyran-6-boronic 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.

3,4-Dihydro-2<I>H</I>-pyran-6-boronic acid pinacol ester (CAS 1025707-93-0), molecular formula C11H19BO3 and molecular weight 210.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4-Dihydro-2<I>H</I>-pyran-6-boronic acid pinacol ester (C11H19BO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
