Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. It serves as a building block in the preparation of bioactive molecules due to its ability to act as a linker or spacer with conformational flexibility. Commonly employed in medicinal chemistry for modifying pharmacokinetic properties such as solubility and metabolic stability. Also utilized in the creation of receptor ligands, especially for serotonin and dopamine receptors, making it relevant in the research of neuropharmacological drugs.
