Daunomycin hydrogen halide salts of high purity are prepd. via crystalline daunomycin formate, from daunomycin base and formic acid or via the acetate. A salt is formed with anhydrous hydrogen-halide from the base, liberated in an non-polar solvent, opt. diluted by an 1-4C alcohol. This is opt. recrystallised from a chlorinated hydrocarbon and a 1-4C alcohol mixt. Conversely, daunomycin base liberated in aq. medium from its formate or acetate is dissolved in a non-polar solvent. The soln. is opt. diluted by an 1-4C alcohol and the salt is formed with anhydrous hydrogen-halide and opt. recrystallised from a mixt. of chlorinated hydrocarbon and 1-4C alcohol.(Dwg.0/1)
