Product Description: I2959 is widely used as a photoinitiator for photochemical cross-linking of hydrogels, and the combination of I2959 and CMA hydrogel has been used as a bio-ink for biological 3D printing applications. In addition, I2959 has a high free radical generation efficiency and is cytotoxic to rapidly dividing cell lines[1].
Formula: C12H16O4
