What is 2,3-BENZOFLUORENE?

Chemical properties

ALMOST WHITE TO YELLOW-GREEN CRYSTALLINE POWDER

The Uses of 2,3-BENZOFLUORENE

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.
