Chemical Structure

4-Bromo-3,5-difluoro-2-nitroaniline CAS 1823960-65-1 chemical structure

Description

The occurrence of 4-Bromo-3,5-difluoro-2-nitroaniline is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Bromo-3,5-difluoro-2-nitroaniline (CAS 1823960-65-1), a certified reference material (molecular formula C6H3BrF2N2O2, MW 253.00 g/mol) for analytical method development and quality control.

The molecular framework of 4-Bromo-3,5-difluoro-2-nitroaniline (C6H3BrF2N2O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 4-Bromo-3,5-difluoro-2-nitroaniline 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.
