Chemical Structure

(4-Bromo-6-chloropyridin-3-yl)boronic acid CAS 957062-85-0 chemical structure

Description

The occurrence of (4-Bromo-6-chloropyridin-3-yl)boronic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4-Bromo-6-chloropyridin-3-yl)boronic acid (CAS 957062-85-0), molecular formula C5H4BBrClNO2 and molecular weight 236.26 g/mol, is a CATO reference standard with documented purity and traceability.

(4-Bromo-6-chloropyridin-3-yl)boronic acid (C5H4BBrClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), (4-Bromo-6-chloropyridin-3-yl)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.
