Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for anti-inflammatory and analgesic drugs. It serves as a building block in organic reactions where the aldehyde group enables condensation or reduction to form more complex molecules. Its chlorinated and benzyloxy-substituted aromatic structure makes it valuable in constructing heterocyclic compounds used in medicinal chemistry. Also employed in the preparation of agrochemicals and specialty polymers due to its reactivity and structural stability.
