4-nitrosodiphenylamine

4-Nitrosodiphenylamine (CAS 156-10-5 ), also known as p-Nitrosodiphenylamine, is an aromatic amine compound used primarily as a stabilizer and antidegradant in polymer and rubber processing.

It functions by inhibiting oxidative degradation, extending the service life of finished materials under heat and mechanical stress. In rubber compounding, it acts as a prevulcanization inhibitor and antidegradant.

This chemical helps processors control cure onset timing while protecting the compound during mixing and storage. Tire manufacturers incorporate it into tread and sidewall formulations where oxidative breakdown must be minimized.

In plastics processing, it is used to stabilize polymer intermediates and finished articles exposed to elevated temperatures during extrusion or molding. It also serves as a building block in the synthesis of additives.

These complex antioxidant and antiozonant additives are used across rubber goods production. 4-Nitrosodiphenylamine is typically supplied as a solid powder or crystalline material for industrial use.

Technical grade is the standard commercial form for industrial rubber and polymer applications. It is available in bulk quantities suited to compounding operations for various manufacturing needs.

Packaging options range from bags to drums depending on volume requirements. This ensures safe handling and efficient storage for large-scale chemical processing and material science applications.
