  • PROCESS FOR PREPARING A TETRAZOLE-SUBSTITUTED ANTHRANILIC ACID DIAMIDE DERIVATIVE
    Publication number: 20230339899
    Abstract: The present invention relates to a process for preparing a tetrazole-substituted anthranilic acid diamide derivative according to formula (I) in crystalline form via solvate crystals in high purity and high yield. The present invention also further relates to the provision of novel solvate crystals which are distinguished by improved filtration properties compared to a tetrazole-substituted anthranilic acid diamide derivative according to the abovementioned formula (I) in crystalline form.

  • DEVICE FOR FILTRATION, DRYING AND STORAGE
    Publication number: 20140317951
    Abstract: The invention relates to a device for filtration, drying and storage of solids from a suspension (FDS unit) and a method carried out in this system for the downstream processing of a solids suspension, in particular of crystallizable therapeutic proteins or active ingredients. The FDS unit, designed for use as a disposable system, is a device with which active ingredient crystals can be gently and safely filtered, dried, stored and reconstituted in a closed process procedure, i.e. without intermediate opening or transfer.
