What Is Aniline?

Aniline (CAS 62-53-3), also called phenylamine, is a colorless to pale yellow liquid with the formula C₆H₇N. It is a weak base and one of the most important aromatic amine intermediates in the chemical industry.

Main Applications

• MDI & Polyurethane: Over 85% of aniline is used to make MDI, a key raw material for rigid and flexible polyurethane foams.

• Rubber Chemicals: Used in accelerators for tires and rubber products.

• Dyes & Pigments: A base for many azo dyes.

• Pharmaceuticals & Agrochemicals: Used in sulfa drugs, paracetamol, and herbicides.

Market Snapshot

• Global aniline market: USD 10.17 billion in 2025 → USD 13.27 billion by 2030, CAGR 5.5%.

• Asia dominates with about 52.9% of global demand.

• Growth is driven by construction, automotive, and tire manufacturing.

Safety & Handling

• Toxic if swallowed, inhaled, or absorbed through skin.

• Causes serious eye damage; suspected carcinogen (IARC Group 2A).

• Use PPE, proper ventilation, and sealed storage away from light.

• UN 1547, Class 6.1; HS Code 2921.41.

Buying Aniline

• Purity: ≥99.0% to ≥99.95%

• Packaging: 200L drums, ISO tanks, or bulk

• Verify REACH/SDS, purity specs, and supply reliability
