Used in the synthesis of pharmaceuticals, particularly in the production of certain vasodilators and cardiovascular drugs. It serves as an intermediate in organic reactions where aldehyde functionality allows for the formation of carbon-carbon bonds, enabling the construction of more complex molecules. Commonly employed in the preparation of fragrances and flavoring agents due to its aromatic character. Also utilized in the development of agrochemicals and dyes, where it acts as a building block for heterocyclic compounds. Its reactivity makes it valuable in research laboratories for exploring new synthetic pathways.
