This chemical is widely used in the field of photodynamic therapy (PDT) due to its ability to generate reactive oxygen species (ROS) when exposed to light. It serves as a photosensitizer, targeting and destroying cancer cells with minimal damage to surrounding healthy tissue. Additionally, it is employed in the development of advanced materials for light-harvesting systems, such as solar cells, owing to its strong light absorption properties. Its carboxymethyloxy groups enhance solubility and enable functionalization, making it suitable for use in biosensors and diagnostic imaging. Researchers also utilize it in catalysis for organic transformations, leveraging its porphyrin structure to facilitate efficient reactions.
