Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for introducing the 2-methylpropanoic acid moiety with a bromine functional handle, enabling further derivatization through substitution or coupling reactions. Commonly employed in the synthesis of active ingredients in crop protection agents and in the development of ibuprofen and related anti-inflammatory compounds. Also utilized in the preparation of specialty polymers and esters for fragrances and flavorings.
