2-Bromo-5-cyano-3-hydroxybenzoic acid CAS 1805487-23-3

Description

Compared with other compounds in its class, the molecular weight of 242.03 g/mol gives 2-Bromo-5-cyano-3-hydroxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromo-5-cyano-3-hydroxybenzoic acid (CAS 1805487-23-3), molecular formula C8H4BrNO3 and molecular weight 242.03 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Bromo-5-cyano-3-hydroxybenzoic acid (C8H4BrNO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-Bromo-5-cyano-3-hydroxybenzoic 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.
