7,14-Dibenzpyrenequinone is a yellow synthetic anthraquinone vat dye, known as Vat Yellow 4. It is a bright yellow solid. This dye is used mostly as a dye for textiles and paper. Together with benzanthrone, it is used in some older pyrotechnic compositions for green and yellow colored smokes. It is produced from 1,5-dibenzoylnaphthalene by oxidative (dehydrogenative) ring closure.

Safety

Vat Yellow 4 is a Group 3 carcinogen according to the IARC, as the evidence of its carcinogenity to humans is inadequate.
