Oxazole - Oxazole (English spelling)

A general term for five-membered heteroaromatic ring compounds with one oxygen atom and one nitrogen atom in the ring. There are two isomers, 1,3-oxazole and 1,2-oxazole, the latter of which is often called isoxazole, and when simply called oxazole, it refers to 1,3-oxazole. This compound is obtained by decarboxylation of 1,3-oxazole-4-carboxylic acid. It is a colorless liquid with a foul odor similar to pyridine, and is volatile. It is miscible with water and is weakly basic.
