Used primarily in pharmaceutical research and development, this compound serves as a key intermediate in the synthesis of various active pharmaceutical ingredients (APIs). It is particularly valuable in the production of drugs that target the central nervous system, including sedatives and antihistamines. Additionally, it finds application in the preparation of quaternary ammonium compounds, which are widely used in disinfectants and surfactants. Its role in organic synthesis extends to the creation of complex molecules for medicinal chemistry, where it aids in the introduction of diethylamino functional groups.
