Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for various therapeutic areas. It plays a role in the production of compounds with potential antibacterial, antiviral, or anticancer properties. Additionally, it is utilized in organic synthesis to create complex molecules for research and industrial applications, including agrochemicals and fine chemicals. Its aldehyde group makes it a versatile building block for constructing heterocyclic compounds, which are important in medicinal chemistry.
