Chemical Structure

2-Bromo-1,3-dichloro-4,5-dinitrobenzene CAS 99979-71-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-1,3-dichloro-4,5-dinitrobenzene.

2-Bromo-1,3-dichloro-4,5-dinitrobenzene (CAS 99979-71-2), molecular formula C6HBrCl2N2O4 and molecular weight 315.89 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Bromo-1,3-dichloro-4,5-dinitrobenzene (C6HBrCl2N2O4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. 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), 2-Bromo-1,3-dichloro-4,5-dinitrobenzene 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.
