CAS 26833-87-4 — Homoharringtonine

Homoharringtonine is a natural alkaloid derived from the evergreen tree *Cephalotaxus harringtonia*, primarily used in cancer research and clinical applications for its potent anti-leukemic properties, particularly in treating chronic myeloid leukemia. It inhibits protein synthesis by binding to the S6 ribosomal RNA, disrupting tumor cell growth. This compound has a CAS number of 26833-87-4, with the molecular formula C29H39NO9 and a molecular weight of 545.62 g/mol. It must be stored at -15 to -20°C and is classified with a **Danger** signal word due to its toxicity. Molekula supplies Homoharringtonine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
