GENERAL DESCRIPTION AND APPLICATIONS |
||
| Oxazole is a heterocyclic organic compound that has a five-member ring molecular structure,C3H3ON, containing three carbon atoms, one oxygen atom, and one nitrogen atom. It is a clear to yellowish liquid with a pyridine like odor. It is soluble in alcohol and ether and slightly soluble in water. Oxazole and its derivatives are used as building block for biochemicals and pharmaceutical as well as in other industrial applications such as pesticides, dyes, fluorescent brightening agents, textile auxiliaries and plastics. The term of isoxazole is for 1,2-oxazole. An example of end-product from 5-methylisoxazole-4-carboxylic acid is leflunomide, dihydroorotate dehydrogenase(DHODH) inhibitor. | ||
