Product Information
Description: Captisol is a unique reproducible mixture of polyanionic β-cyclodextrin derivatives in which a sodium sulfonate salt is tethered to the lipophilic cyclodextrin cavity by a butyl ether group, or sulfobutylether (SBE).
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials at -20°C or below and used within 1 month.
