Chemical Structure

(4-(O-tolyl)furan-2-yl)boronic acid CAS 2096339-58-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-(O-tolyl)furan-2-yl)boronic acid.

(4-(O-tolyl)furan-2-yl)boronic acid (CAS 2096339-58-9), molecular formula C11H11BO3 and molecular weight 202.01 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H11BO3, (4-(O-tolyl)furan-2-yl)boronic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 202.01 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.

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.
