Used as a photosensitizer in photodynamic therapy, particularly in experimental cancer treatments. It enhances the cytotoxic effects of light exposure on tumor cells by generating reactive oxygen species. Also investigated for use in photochemical tissue bonding and wound closure applications due to its ability to promote cross-linking in biological tissues under specific light activation. Shows potential in ophthalmic surgeries and dermatology where precise, non-invasive tissue repair is required. Its sulfonate group improves water solubility, making it suitable for intravenous or topical formulations in medical settings.
