Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It plays a key role in the preparation of certain local anesthetics and anti-inflammatory agents due to its ability to introduce specific functional groups in organic reactions. Its reactivity makes it valuable in forming carbon-carbon bonds through nucleophilic substitution or condensation processes. Commonly employed in research laboratories for developing novel bioactive compounds. Handling requires caution due to its lachrymatory and irritant properties.
