4,7-Bis[5-bromo-4-(2-ethylhexyl)-2-thienyl]-5,6-difluoro-2-(2-hexyldecyl)-2H-benzotriazole CAS 2239298-37-2

Description

4,7-Bis[5-bromo-4-(2-ethylhexyl)-2-thienyl]-5,6-difluoro-2-(2-hexyldecyl)-2H-benzotriazole (C46H69Br2F2N3S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
