👉 Benzoquinone is a chemical compound that consists of two benzoxazole rings. It is commonly used in organic chemistry and biochemistry to denote the presence or absence of certain functional groups, such as hydroxyl (OH) or carboxylic acid. The term "benzoquinone" is derived from the chemical formula C10H9NO2, which can be further simplified to C7H8N3O2 by removing the oxygen atoms.
