  • Applications

    Thiothixene (USAN:USP), CAS 5591-45-7, is a thioxanthene derivative primarily used as a pharmaceutical active ingredient in antipsychotic medications; apart from its API role, it is employed as a building block in medicinal chemistry for the synthesis and evaluation of thioxanthene derivatives, used as a reference material for analytical method development in pharmaceutical quality control, and supplied as a specialty chemical reagent for research and development of CNS-active compounds.
