Chemical Structure
Description
The occurrence of 1,4-Dibromonaphthalene-2,3-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,4-Dibromonaphthalene-2,3-diamine (CAS 103598-22-7), molecular formula C10H8Br2N2 and molecular weight 315.99 g/mol, is a CATO reference standard with documented purity and traceability.
1,4-Dibromonaphthalene-2,3-diamine (C10H8Br2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 1,4-Dibromonaphthalene-2,3-diamine 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.
