Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nootropic drugs such as piracetam and related racetam family compounds. It plays a key role in constructing the core structure of these cognitive enhancers by enabling the formation of amide or ester linkages through its aldehyde functional group. Also utilized in organic synthesis for developing heterocyclic compounds and in medicinal chemistry for creating analogs with potential neuroprotective or stimulant properties. Its reactivity allows for easy modification, making it valuable in drug discovery and development.
