Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) and other therapeutic agents. It plays a key role in the formation of active pharmaceutical ingredients (APIs) by serving as a building block for complex molecules. Additionally, it is employed in organic synthesis for creating compounds with potential biological activity, aiding in drug discovery and development. Its chloromethyl group makes it a versatile reagent for further functionalization in chemical reactions.
