Used as an intermediate in organic synthesis, particularly in pharmaceutical manufacturing. It serves as a building block for active pharmaceutical ingredients (APIs) due to its stable morpholine ring and reactive cyclopropyl group. Commonly employed in the development of central nervous system agents and antiviral drugs. Its hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction environments. Also utilized in research settings for structure-activity relationship (SAR) studies in medicinal chemistry.
