Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,2-Diamino-4-bromo-5-(trifluoromethyl)benzene (CAS 157590-60-8) is a high-purity analytical reference standard with the molecular formula C7H6BrF3N2 and a molecular weight of 255.04 g/mol.
1,2-Diamino-4-bromo-5-(trifluoromethyl)benzene (C7H6BrF3N2) contains a nitrile group, fluorine/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).
As a certified reference material (CRM), 1,2-Diamino-4-bromo-5-(trifluoromethyl)benzene 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.
