DiZPK is primarily used in biochemical research as a photosensitive compound for studying protein interactions and dynamics. It is particularly valuable in photoaffinity labeling, where it helps in identifying and mapping protein binding sites. When exposed to UV light, DiZPK forms covalent bonds with nearby proteins, allowing researchers to capture transient interactions that are otherwise difficult to study. This makes it a powerful tool in proteomics and drug discovery, enabling the investigation of protein function and the development of targeted therapies. Additionally, its application extends to cellular imaging, where it aids in visualizing protein localization and activity in live cells.
