In order to improve the heat stability and handling, and reduce the hydroscopicity of deoxyspergualin hydrochloride, it is put up in crystalline form rather than a lyophilized powder. The crystals are formed by crystallizing a conventionally prepared powder or aqueous syrup of deoxyspergualin by standing in a low humidity atmosphere, possibly in the presence of a water-soluble or water miscible organic solvent.
