Chemical Structure
Description
The occurrence of 3,4-Dibromobenzonitrile is closely related to a nitrile group, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,4-Dibromobenzonitrile (CAS 188984-35-2), molecular formula C7H3Br2N and molecular weight 260.91 g/mol, is a CATO reference standard with documented purity and traceability.
3,4-Dibromobenzonitrile (C7H3Br2N) contains a nitrile group, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 3,4-Dibromobenzonitrile 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.
