Benzene 71-43-2

Benzene (CAS 71-43-2, C6H6), is a colorless liquid, widely used in the production of various chemicals, including plastics, resins, synthetic fibers, rubber, dyes, detergents, and pharmaceuticals. It has a distinct aromatic odor and is highly flammable. Benzene is known for its unique structure, consisting of a ring of six carbon atoms, each bonded to a hydrogen atom. This cyclic arrangement of atoms gives benzene its stability and reactivity, making it an important building block in organic chemistry. Benzene is a key component in the production of many everyday products and plays a crucial role in various industries, such as petrochemicals, pharmaceuticals, and manufacturing.
