Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of fragrances and bioactive molecules. Its aldehyde functionality allows for condensation reactions, making it valuable in forming carbon-carbon bonds during organic synthesis. Commonly employed in the preparation of benzodiazepine derivatives and other heterocyclic compounds with potential medicinal properties. Also utilized in research settings for the design of novel organic materials and as a building block in asymmetric synthesis.
