Description
Compared with other compounds in its class, the molecular weight of 562.97 g/mol gives Tris(4-bromo-2,6-dimethylphenyl)borane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tris(4-bromo-2,6-dimethylphenyl)borane (CAS 1239448-99-7) is a high-purity analytical reference standard with the molecular formula C24H24BBr3 and a molecular weight of 562.97 g/mol.
Tris(4-bromo-2,6-dimethylphenyl)borane (C24H24BBr3) contains bromine substitution, a polycyclic aromatic system. 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).
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), Tris(4-bromo-2,6-dimethylphenyl)borane 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.
