What is "benzoxazole"

n. (context organic compound English) A bicyclic heterocycle consisting of a benzene ring fused to that of oxazole

Benzoxazole is an aromatic organic compound with a molecular formula CHNO, a benzene-fused oxazole ring structure, and an odor similar to pyridine. Alhtough benzoxazole itself is of little practical value, many derivatives of benzoxazoles are commercially important.

Being a heterocyclic compound, benzoxazole finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.
