The mechanism of action is not clear, but it may inhibit the production of prostaglandin or have other effects on cell metabolism. Pigment Red 4 has also been used in the manufacture of lacquers and enamels because it resists corrosion by water and dilute acids. This pigment can also be mixed with boron nitride to form a chelate ligand that is used in laser ablation.
