2-[(E)-2-nitro-2-phenyl-ethenyl]thiophene 2-[(E)-2-nitro-2-phenylethenyl]thiophene 5411-70-1 A829972 (CAS 5411-70-1) is a high-purity analytical reference standard with the molecular formula C8H8Br4O4 and a molecular weight of 487.76 g/mol.
2-[(E)-2-nitro-2-phenyl-ethenyl]thiophene 2-[(E)-2-nitro-2-phenylethenyl]thiophene 5411-70-1 A829972 (C8H8Br4O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
