Applications in the pharmaceutical field: As a pharmaceutical intermediate, it can be involved in the synthesis of various drugs. For example, in the production of certain drugs for treating cardiovascular diseases, sodium iminodipropionate can serve as a key structural unit, contributing to the formation of molecular structures with specific pharmacological activities. In the chemical industry: It is an important raw material for the preparation of chelating agents. The resulting chelating agents can form stable complexes with metal ions. In the textile and dyeing industry, they can be used to remove heavy metal ions from water, preventing these ions from affecting the dyes and improving the dyeing quality. In the paper industry, they can be used to treat metal impurities in pulp, thereby enhancing the quality of the paper. In the field of biochemistry: In biological experiments, it can be used as a component of buffer systems to maintain a stable pH value, providing a suitable environment for biochemical reactions. Additionally, in the study of certain enzymes, it may act as an auxiliary reagent, affecting the activity and stability of the enzymes and aiding in a deeper understanding of their mechanisms of action.
