Use
Isobutyric acid is mainly used in the synthesis of isobutyric acid esters, such as methyl isobutyrate, propyl ester, isoamyl ester and benzyl ester. It can also be used manufacture of esters for solvents, flavors and perfume bases, disinfecting agent, varnish, plasticizers, deliming hides, tanning agent and used in pharmaceutical. Isobutyric acid has some important derivatives that, in the industry, is actually used for the production of isobutyronitrile intermediates, and then converted to isobutylamidine hydrochloride that is the raw materials of pesticide diazinon.
