This chemical is primarily used in the field of photodynamic therapy (PDT) due to its porphyrin structure, which is effective in generating reactive oxygen species (ROS) when exposed to light. It is applied as a photosensitizer in cancer treatment, where it targets and destroys malignant cells upon light activation. Additionally, it is utilized in the development of advanced materials for organic electronics, such as organic light-emitting diodes (OLEDs) and solar cells, owing to its ability to facilitate electron transfer and light absorption. In research, it serves as a building block for synthesizing complex porphyrin-based compounds for studying light-induced chemical reactions.
