High purity phthalein derivatives and method for preparing same |
| abstract |
The invention concerns high purity phthalcin derivatives enabling their use for medical applications or in the field of biotechnology, as well as their preparation method whereby a phthatic 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. |
