**Applications in the pharmaceutical industry:** It is an important pharmaceutical intermediate that can be used in the synthesis of various drugs. For example, it can serve as a raw material for the production of certain antibiotics and cardiovascular medications, playing a key role in the structural construction during the drug synthesis process. **Applications in the chemical industry:** It can be used to manufacture chemical products such as chelating agents and surfactants. As a chelating agent, it is capable of forming stable complexes with metal ions, which makes it widely applicable in fields such as water treatment and metal processing. It can be used to remove heavy metal ions from water or to provide protection and stability during metal surface treatment. **Applications in biochemistry:** In biochemical research, iminodipropionic acid can be used as one of the components of buffers to maintain the stability of the pH value in biological reaction systems. Additionally, it may be involved in the study of certain metabolic processes, acting as a substrate or inhibitor for certain enzymes, which helps to gain a deeper understanding of the chemical reaction mechanisms within living organisms.
