b-Cyclodextrin sulfobutyl ether sodium salt , Sodium sulphobutylether-b-cyclodextrin; SBECD; SBE4-b-CyD?-cyclodextrin sulfobutyl ether is an excipient compound incorporating a chemically modified cyclodextrin with a structure that optimises the solubility and stability of active pharmaceuticals and their properties. It is a highly water-soluble anionic cyclodextrin derivative. It can easily form non-covalent inclusion complexes with drug molecules and therefore reduce drug toxicity and haemolysis as well as control drug release rate. Its complexing properties also make it suitable for masking unpleasant odours and tastes of pharmaceutical products. It is used as an excipient in injection, oral, nasal and eye medication.?CAS No182410-00-0SynonymsSodium sulphobutylether-b-cyclodextrinChemical FormulaC70H119Na7O56S7Molecular Weight2,242.05 g/molSmiles[Na+].[Na+].[Na+].[Na+].[Na+].[Na+].[Na+].OC1[C@@H](O)[C@@H]2O[C@H]3OC(COCCCCS(=O)(=O)[O-])[C@@H](O[C@H]4OC(COCCCCS(=O)(=O)[O-])[C@@H](O[C@H]5OC(COCCCCS(=O)(=O)[O-])[C@@H](O[C@@H]6OC(COCCCCS(=O)(=O)[O-])[C@@H](O[C@H]7OC(COCCCCS(=O)(=O)[O-])[C@@H](O[C@H]8OC(COCCCCS(=O)(=O)[O-])[C@@H](O[C@H]1OC2COCCCCS(=O)(=O)[O-])[C@H](O)C8O)[C@H](O)C7O)[C@H](O)C6O)[C@H](O)C5O)[C@H](O)C4O)[C@H](O)C3OStoragestore at 2?C – 8?C, close container wellGHS InformationGHS Code GHS07Harmonized Tariff CodesSwitzerland: 29400090 – USA: 2940006000 – Slovakia: 2940000080 – UK: 2940000000 – China: 3505100000
