Description | Benzoxazole, also known as 1,3-Benzoxazole or 1-Oxa-3-azaindene, is a member of the class of compounds known as benzoxazoles. Benzoxazoles are organic compounds containing a benzene fused to an oxazole ring. Oxazole is five-membered aromatic ring with a nitrogen and an oxygen atom at the 1- and 3-position, respectively. Benzoxazole is soluble (in water) and has an odor similar to pyridine. Although benzoxazole itself is of little practical value, many derivatives of benzoxazoles are commercially important. Being a heterocyclic compound, benzoxazole is commonly used as a starting material for the synthesis of larger, bioactive structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization. Benzoxazole is found within the chemical structures of pharmaceutical drugs such as flunoxaprofen and tafamidis. Benzoxazole occurs naturally and can be found in roast beef and tea, which makes benzoxazole a potential biomarker for the consumption of this food product. Benzoxazole is formed during the combustion of cannabis and is therefore a constituent of cannabis smoke ( Ref:DOI ). |
