2,3-BENZOFLUORENE Chemical Properties,Usage,Production
Chemical Properties
ALMOST WHITE TO YELLOW-GREEN CRYSTALLINE POWDER
Uses
2,3-Benzofluorene was used in three way analysis of fluorescence excitation-emission matrices of mixtures of polycyclic aromatic hydrocarbons. It was used as standard to detect the ambient particle-bound polycyclic aromatic hydrocarbons by a real-time aerosol mass spectrometer.
Definition
ChEBI: Benzo[b]fluorene is a carbotetracyclic compound.
Synthesis Reference(s)
The Journal of Organic Chemistry, 53, p. 904, 1988 DOI: 10.1021/jo00239a050
General Description
2,3-Benzofluorene was identified in a coal liquid (solvent-refined coal) product by synchronous fluorescence and the room-temperature phosphorescence methods. It inhibits estradiol-dependent reporter activity in yeast.
Safety Profile
Mutation data reported.Questionable carcinogen. When heated to decompositionit emits acrid smoke and irritating vapors.
Carcinogenicity
Benzo[b]fluoranthene gave a positive result in one two-stage carcinogenesis test in mice.
