Chemical Structure
Description
1,3,5,9-Tetrabromo-7-(tert-butyl)pyrene (C20H14Br4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1,3,5,9-Tetrabromo-7-(tert-butyl)pyrene (CAS 1422738-41-7), molecular formula C20H14Br4 and molecular weight 573.94 g/mol, is a CATO reference standard with documented purity and traceability.
