Chemical Structure
Description
2,6-Dibromo-9,10-bis(9,9-dimethyl-9H-fluoren-2-yl)anthracene (CAS 1154751-57-1) is a high-purity analytical reference standard with the molecular formula C44H32Br2 and a molecular weight of 720.53 g/mol.
2,6-Dibromo-9,10-bis(9,9-dimethyl-9H-fluoren-2-yl)anthracene (C44H32Br2) 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), 2,6-Dibromo-9,10-bis(9,9-dimethyl-9H-fluoren-2-yl)anthracene 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.
