Perylene or perilene is a polycyclic aromatic hydrocarbon with the chemical formula C20H12, occurring as a brown solid. It or its derivatives may be carcinogenic, and it is considered to be a hazardous pollutant. In cell membrane cytochemistry, perylene is used as a fluorescent lipid probe. It is the parent compound of a class of rylene dyes.

Perylene in the context of Rylene dye
A rylene dye is a dye based on the rylene framework of naphthalene units linked in peri-positions. In homologues additional naphthalene units are added, forming compounds — or poly(peri-naphthalene)s — such as perylene, terrylene and quarterrylene.

Pigment Violet 29 (C.I. 71129) is an organic compound that is used as a pigment and vat dye. Its colour is dark red purple, or bordeaux.
Structurally, it is a derivative of perylene, although it is produced from acenaphthene. It is a less common dye compared to related derivatives such as pigment red 190 (Vat Red 29).
