5-Chloro-2-hydroxyphenylboronic Acid CAS 89488-25-5

Description

The occurrence of 5-Chloro-2-hydroxyphenylboronic 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.

5-Chloro-2-hydroxyphenylboronic Acid (CAS 89488-25-5) is a high-purity analytical reference standard with the molecular formula C6H6BClO3 and a molecular weight of 172.37 g/mol.

5-Chloro-2-hydroxyphenylboronic Acid (C6H6BClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 5-Chloro-2-hydroxyphenylboronic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
