Substance Name: Cyclophosphamide [USP:INN]
RN: 50-18-0
UNII: 6UXW23996M
InChIKey: CMSMOCZEIVJLDB-UHFFFAOYSA-N

Note

  • Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active ALDOPHOSPHAMIDE. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
