Chemical Structure

1-Cyclopenteneboronic Acid Pinacol Ester CAS 287944-10-9 chemical structure

Description

Based on its molecular formula C11H19BO2, 1-Cyclopenteneboronic Acid Pinacol Ester contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 194.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1-Cyclopenteneboronic Acid Pinacol Ester (CAS 287944-10-9) is a high-purity analytical reference standard with the molecular formula C11H19BO2 and a molecular weight of 194.08 g/mol.

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), 1-Cyclopenteneboronic 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.
