Quinones

Quinones are an important class of organic compounds, mainly composed of two or more benzene rings linked by a carbonyl group. They are widely used in the synthesis of polymers and other materials, such as polyurethanes and polyesters. Quinones are also used in the manufacture of dyes, medicines, and other organic compounds. They are also used as antioxidants and in the production of biofuels. Quinones are important components of many natural products, such as plant pigments, and are also used in the production of food additives.
