    Product Description

    77PD is a substituted p-phenylenediamine.1 It scavenges ozone, forming nitroxyl radicals. 77PD is toxic to the aquatic bacterium V. fischeri (EC50 = 0.41 mg/L) and has been found in river water and sediment.2,3 77PD has been used as an antiozonant in rubber tires.4

    WARNING This product is not for human or veterinary use.
