(2-Chloro-5-hydroxyphenyl)boronic acid CAS 913835-71-9

Description

The occurrence of (2-Chloro-5-hydroxyphenyl)boronic 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-Chloro-5-hydroxyphenyl)boronic acid (CAS 913835-71-9), molecular formula C6H6BClO3 and molecular weight 172.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (2-Chloro-5-hydroxyphenyl)boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-Chloro-5-hydroxyphenyl)boronic 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.
