Diphenylamine has been chosen for a variety of uses, primarily due to its chemical properties and applications. Some common purposes include:
1) Use as antioxidant: Diphenylamine is often used as an antioxidant in the rubber industry. It helps prevent rubber degradation by inhibiting the formation of harmful oxidation products.
2) Used as an indicator: Diphenylamine develops a unique blue color when it reacts with certain analytes. It is often used as an indicator in chemical analysis to determine the presence or absence of a specific substance.
3) Use in Explosives: Diphenylamine is a component of some types of explosives and propellants. It acts as a stabilizer and helps prevent explosive materials from breaking down or degrading.
4) Use in the synthesis of organic compounds: Diphenylamine is often used as a precursor or starting material for the synthesis of various organic compounds. It can undergo various reactions to form different products with desired properties.

Overall, the purpose of selecting diphenylamine depends on the user’s specific application or requirements.
