  • Applications

    (-)-Isosclerone (CAS 137494-04-3) is a chiral organic compound that is typically used as an intermediate and building block in organic synthesis. In pharmaceutical research, it may serve as a starting material for asymmetric synthesis of bioactive compounds and as a scaffold for developing complex molecules. It is also evaluated as an intermediate in agrochemical research and other specialty chemical syntheses. In process development and laboratory studies, it can function as a reagent for method optimization and for preparing derivatives, and may be considered for natural product type synthesis programs. Its specific applications depend on local regulations and formulation constraints.
