Chemical Structure
Description
2,2′:7′,2′′-Ter-9H-fluorene, 7-bromo-9,9,9′,9′,9′′,9′′-hexaoctyl- (CAS 409093-95-4) is a high-purity analytical reference standard with the molecular formula C87H121Br and a molecular weight of 1246.80 g/mol.
Owing to bromine substitution, a polycyclic aromatic system, 2,2′:7′,2′′-Ter-9H-fluorene, 7-bromo-9,9,9′,9′,9′′,9′′-hexaoctyl- is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1246.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
