Chemical Structure

1,5-DIBROMO-2,4-DINITROBENZENE CAS 24239-82-5 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 1,5-DIBROMO-2,4-DINITROBENZENE.

1,5-DIBROMO-2,4-DINITROBENZENE (CAS 24239-82-5) is a high-purity analytical reference standard with the molecular formula C6H2Br2N2O4 and a molecular weight of 325.90 g/mol.

The molecular framework of 1,5-DIBROMO-2,4-DINITROBENZENE (C6H2Br2N2O4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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).

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), 1,5-DIBROMO-2,4-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.
