Chemical Structure

cyclopropylmethylboronic acid CAS 2254220-74-9 chemical structure

Description

Based on its molecular formula C4H9BO2, cyclopropylmethylboronic acid 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 99.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

cyclopropylmethylboronic acid (CAS 2254220-74-9) is a high-purity analytical reference standard with the molecular formula C4H9BO2 and a molecular weight of 99.92 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
