Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. Its structure allows for functionalization into active compounds with potential antidepressant or anticonvulsant activity. Also employed in the preparation of chiral building blocks for asymmetric synthesis, making it valuable in medicinal chemistry and drug discovery. Its aldehyde group enables easy conversion into alcohols, acids, or amines, facilitating diverse molecular transformations.
