Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 436.22 g/mol gives 2,7-Dibromo-3,6-di-tert-butyl-9H-fluorene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,7-Dibromo-3,6-di-tert-butyl-9H-fluorene (CAS 106112-41-8) is a high-purity analytical reference standard with the molecular formula C21H24Br2 and a molecular weight of 436.22 g/mol.
2,7-Dibromo-3,6-di-tert-butyl-9H-fluorene (C21H24Br2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 2,7-Dibromo-3,6-di-tert-butyl-9H-fluorene 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.
