white crystals or light brown powder

??

Carbazole and its derivatives are widely used as an intermediate in synthesis of pharmaceuticals, agrochemicals, dyes, pigments and other organic compounds.carbazole is also used in luminescence chemistry as a photosensitizing and additional charge transport material. Carbazole structure is a motif in pharmaceuticals such as carvedilol used to treat high blood pressure and to prevent cardiac arrhythmias and angina.

??

carbazole: A white crystalline compoundfound with anthracene,C12H9N; m.p. 238°C; b.p. 335°C. It isused in the manufacture of dyestuffs.

?? ??

White crystals, plates, leaflets or light tan powder. Sublimes readily. Exhibits strong fluorescence and long phosphorescence on exposure to ultraviolet light.

??? ?? ??

Insoluble in water.

?? ???

Carbazole is an extremely weak base. Carbazole is incompatible with strong oxidizing agents. Carbazole reacts with nitrogen oxides. Potassium hydroxide fusion yields a salt.

???

Possible carcinogen.

????

Flash point data for Carbazole are not available; however, Carbazole is probably combustible.

Safety Profile

intraperitoneal route. A flammable liquid.

Purification Methods

Dissolve carbazole (60g) in conc H2SO4 (300mL), extract with three 200mL portions of *benzene, then stir this into 1600mL of an ice-water mixture. The precipitate is filtered off, washed with a little water, dried, recrystallised from *benzene and then from pyridine/*benzene [Feldman et al. J Am Chem Soc 73 4341 1951]. It has also been recrystallised from EtOH or toluene, sublimed in vacuum, zone-refined, and purified by TLC. [UV: Armarego in Physical Methods in Heterocyclic Chemistry (Ed Katritzky, Academic Press) Vol III 158 1971, Beilstein 20/8 V 9.]
