Diphenylamine sulfate is widely used as a stabilizer in the production of explosives, particularly for nitrocellulose-based propellants. It helps prevent the decomposition of these materials, ensuring their safe storage and handling over time. In the agricultural sector, it serves as an antioxidant in the preservation of fruits, particularly apples, to prevent scald during storage. Additionally, it is employed in the rubber industry as an antiozonant to protect rubber products from degradation caused by exposure to ozone. Its antioxidant properties also make it useful in the stabilization of certain industrial oils and lubricants, enhancing their longevity and performance.
