Bindone is an organic compound with the formula C₆H₄COCH₂C=C(CO)₂C₆H₄. A yellowish solid, it is classified as an aromatic triketone.

Bindone is used as a colour test for the detection of primary amines. It turns violet in their presence. Aromatic amines turn this reagent blue.^[2]

Bindone can be prepared by the condensation of two equivalents of 1,3-indandione.^[3]
