Chemical Structure
Description
The occurrence of 5-Chloro-3-(meththio)phenylboronic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Chloro-3-(meththio)phenylboronic acid (CAS 1451392-52-1) is a high-purity analytical reference standard with the molecular formula C7H8BClO2S and a molecular weight of 202.47 g/mol.
Based on its molecular formula C7H8BClO2S, 5-Chloro-3-(meththio)phenylboronic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 202.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
