Perinone is a class of organic compounds. The parent compound has two isomers, each of which are useful pigments.

It is prepared from naphthalenetetracarboxylic dianhydride by condensation with o-phenylenediamine. The two Isomers of perinone^[1] are useful pigments. The trans isomer is called Pigment Orange 43 ("PO43", CID 78141 from PubChem) and the cis isomer is called Pigment Red 194 ("PR194", CID 77892 from PubChem).^[2] Like some structurally related compounds perinone is also an organic semiconductor.^[3]
