| Use | Used as analytical reagent, redox indicator and liquid desiccant, and also used in the synthesis of organic dyes Mainly used in the manufacture of rubber anti-aging agent, gunpowder stabilizer, and also used as an intermediate for dyes and pesticides The main use of diphenylamine is in the field of rubber chemicals, used in the production of antioxidants, inhibitors, and accelerators; as a dye intermediate, it can produce acid yellow G, acid orange N, acid ink blue A, dispersed blue 5R and other products. It is also an intermediate of plastic stabilizer, veterinary drug sulfide diphenylamine and phenothiazine. Diphenylamine is also used as a stabilizer, analytical reagent, redox indicator and liquid desiccant for nitrocellulose and smokeless explosives. Verification of nitrate, chlorate and other oxidizing substances. Catalytic determination of iridium. Photometric determination of nitrate. Redox indicator. Haploid breeding medium. Making dyes. It is a stabilizer for nitrocellulose, explosives, and cotton. |
