  • Applications

    Liensinine (CAS 2586-96-1) is a bisbenzylisoquinoline alkaloid isolated from lotus seeds, primarily considered in natural product research and early-stage pharmaceutical development. In industrial contexts, it is commonly used as an analytical standard or reference material for the quantitative and qualitative analysis of lotus alkaloids by LC-MS and NMR. It may serve as an intermediate or synthetic building block for related alkaloids in chemical synthesis. Additionally, liensinine is studied as a natural component in lotus extracts and can support product development and phytochemical analysis. Its use is subject to local regulations and formulation limits.
