Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its aldehyde functional group allows for easy modification through reactions such as condensation, reduction, or nucleophilic addition, making it valuable in constructing complex organic structures. Commonly employed in medicinal chemistry for building blocks in the design of kinase inhibitors and central nervous system agents. Also utilized in the preparation of chiral compounds for asymmetric synthesis. Its tetrahydropyranyl moiety can act as a protecting group or influence solubility and stability in synthetic pathways.
