Chemical Structure

2,5-Dichlorophenylboronic Acid CAS 135145-90-3 chemical structure

Description

The occurrence of 2,5-Dichlorophenylboronic Acid is closely related to 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.

2,5-Dichlorophenylboronic Acid (CAS 135145-90-3), molecular formula C6H5BCl2O2 and molecular weight 190.82 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H5BCl2O2, 2,5-Dichlorophenylboronic Acid contains 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 190.82 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.

As a certified reference material (CRM), 2,5-Dichlorophenylboronic Acid 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.
