This chemical is primarily used in the field of organic synthesis, particularly in the development of phosphorus-containing compounds. It serves as a key intermediate in the production of organophosphorus pesticides, which are widely applied in agriculture to protect crops from pests and insects. Additionally, it finds application in the synthesis of flame retardants, contributing to the enhancement of fire safety in various materials such as textiles, plastics, and electronics. Its role in the preparation of biologically active molecules also makes it valuable in pharmaceutical research, where it aids in the creation of potential drug candidates.
