Benzoxazole is an aromatic organic compound with a molecular formula C7H5NO, a benzene-fused oxazole ring structure, and an odor similar to pyridine. Benzoxazole has no household use. It is used primarily in industry and research.
Being a heterocyclic compound, benzoxazole finds use in research as a starting material for the synthesis of larger, usually bioactive structures. It is found within the chemical structures of pharmaceutical drugs such as flunoxaprofen.
Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.
