Benzanthrone (BZA) is a polycyclic aromatic hydrocarbon. It is a yellow solid.[1] Its derivatives are used as a dyestuff intermediate for anthraquinone-based dyes.[2] Dehydrogenative coupling gives violanthrone. It is prepared by reduction of anthroquinone to anthrone followed by alkylation with a mixture of glycerol and sulfuric acid.
It is a basic substance with fluorescent and luminescent properties. It can be used for photosensitization, and as a charge transport material. It is also used in pyrotechnics industry, mainly as a component of some older formulations of green and yellow colored smokes, often together with Vat Yellow 4; its US military specification is MIL-D-50074D.[3]
Safety
Benzanthrone causes itching and burning sensations on exposed skin, together with erythema, dermatitis, and skin pigmentation.[4]
