  • Applications

    Girinimbine (CAS 23095-44-5), an alkaloid in the carbazole family isolated from Murraya koenigii, finds niche applications mainly in research and development. It is often studied as a natural lead compound in medicinal chemistry and pharmacological research, and is used as a scaffold or intermediate to prepare carbazole derivatives in organic synthesis. The compound is also explored in agrochemical research for bioactivity relevant to pest control and antimicrobial discovery, while cosmetic and personal-care formulation studies consider it as a bioactive natural product of interest. In analytical workflows, Girinimbine is used as a reference compound in phytochemical analysis and isolation studies to support identification and quality assessment of natural products.
