Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for α-substituted carbonyl compounds due to the presence of both ester and bromo functional groups, enabling transformations such as nucleophilic substitution and cyclization reactions. Commonly employed in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules where the o-tolyl group contributes to steric and electronic properties. Its reactivity allows for easy introduction into heterocyclic systems, making it valuable in medicinal chemistry research and development.
