Aniline is widely used in the production of polyurethane foams, which are essential in manufacturing mattresses, furniture cushions, and insulation materials. It serves as a precursor in the synthesis of methylene diphenyl diisocyanate (MDI), a key component in polyurethane production. In the dye industry, aniline is a fundamental building block for creating a variety of synthetic dyes, including indigo and azo dyes, which are used in textiles, leather, and paper products. It is also utilized in the pharmaceutical sector for producing drugs such as acetaminophen (paracetamol), which is commonly used as a pain reliever and fever reducer. Additionally, aniline is employed in the rubber industry as an antioxidant and vulcanization accelerator, enhancing the durability and performance of rubber products like tires and industrial belts. In agriculture, it is used in the synthesis of herbicides and fungicides, helping to protect crops from pests and diseases. Lastly, aniline finds application in the production of photographic chemicals and as a solvent in certain industrial processes.
