(4-Chloro-3-formylthiophen-2-yl)boronic acid CAS 36155-92-7

Description

The occurrence of (4-Chloro-3-formylthiophen-2-yl)boronic 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.

(4-Chloro-3-formylthiophen-2-yl)boronic acid (CAS 36155-92-7) is a high-purity analytical reference standard with the molecular formula C5H4BClO3S and a molecular weight of 190.41 g/mol.

Based on its molecular formula C5H4BClO3S, (4-Chloro-3-formylthiophen-2-yl)boronic 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 190.41 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.

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.
