Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical industry for the preparation of various active pharmaceutical ingredients (APIs). Its reactivity allows for the introduction of phenylacetic acid derivatives through substitution or coupling reactions. Commonly employed in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other medicinally relevant compounds due to its ability to form carbon-carbon bonds. Also utilized in the production of agrochemicals and fine chemicals where a functionalized aromatic backbone is required. The bromine atom serves as a good leaving group, facilitating nucleophilic substitution under mild conditions.
