  • Applications

    (+)-Isocorydine (CAS 475-67-2) is an aporphine alkaloid primarily used as a synthetic intermediate and a chiral building block in organic synthesis, particularly in medicinal chemistry research and the preparation of aporphine-derived compounds. It is often viewed as a starting material for the preparation of derivatives and as a scaffold for the development of complex synthetic sequences. In analytical chemistry, it may serve as a reference material or standard for chiral separation and structural characterization. Additionally, it is sometimes explored as a ligand or building block for asymmetric catalysis in laboratory settings, subject to regulatory constraints and quality requirements.
