  • (1R, 1?R)-atracurium salts separation process
    Patent number: 8461338
    Abstract: The present invention provides an improved method of chromatographically separating the isomers of (1R,rR)-atracurium salts by high-performance liquid chromatography (HPLC), in the absence of a strong acid. The separation is preferably performed on a silica gel HPLC column using an eluent containing an organic solvent, a polar aprotic co-solvent and a weak organic acid.
