Cas no 1531-77-7 (Homothioxanthone)
Homothioxanthone is a sulfur-containing heterocyclic compound belonging to the thioxanthone family, characterized by its fused tricyclic structure. It is primarily utilized as a photoinitiator in UV-curable coatings, inks, and adhesives due to its efficient absorption in the near-UV range and ability to generate free radicals upon irradiation. The compound exhibits excellent photochemical stability and compatibility with various monomer systems, enabling rapid polymerization under low-energy UV light. Its structural rigidity and electron-delocalization contribute to high reactivity and minimal yellowing in cured formulations. Homothioxanthone is also explored in organic synthesis and photodynamic therapy research owing to its unique photophysical properties.
