1. Synthesis of Drugs and Bioactive Molecules:
In the field of medicinal chemistry research, it serves as an important intermediate in the synthesis of complex natural products and drug molecules. For example, it has been documented in the literature as being used as an alkylating agent in the asymmetric total synthesis of the alkaloid drugs (+)-1-deoxygalanthamine and (+)-galanthamine.

2. Organic Synthesis Building Block:
As a basic “organic building block,” it is widely used to construct more complex organic compounds. It plays a role in various organic synthesis reactions, such as acting as an alkylating agent to modify proteins, enzymes, and other biomolecules.

3. Scientific Research Reagent:
In biochemical and physiological research, it is used to modify biomolecules (such as proteins and enzymes), or to regulate the activity of cell signaling molecules such as neurotransmitters and hormones, in order to study related biological pathways and mechanisms of action.
