Chemical Structure
Description
The molecular framework of 5-Chloro-2,3-dibromoaniline (C6H4Br2ClN) is characterized by a nitrile group, chlorine/bromine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5-Chloro-2,3-dibromoaniline (CAS 96558-70-2) is a high-purity analytical reference standard with the molecular formula C6H4Br2ClN and a molecular weight of 285.36 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-Chloro-2,3-dibromoaniline 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.
