  • High purity phthalein derivatives and method for preparing same
    Patent number: 7994215
    Abstract: High purity phthalein derivatives are useful for medical applications and/or in the field of biotechnology. The phthalein derivatives are prepared by a method whereby a phthalic anhydride derivative is condensed with a naphthol or phenol derivative in an organic acid ester and the crystals of the resulting condensate are converted by action of a strong acid or one of its precursors in anhydrous medium.
    Type: Grant
