Name: Betadex sulfobutyl ether sodium 

CAS No: 182410-00-0

DMF No.: 030167

[Product Description]

Betadex Sulfobutyl Ether Sodium is a sodium salt produced when betacyclodextrin is alkylated by 1,4-butanesulfonic acid lactone under alkaline conditions. It is an anion, highly water-soluble betacyclodextrin derivative. Betadex Sulfobutyl Ether Sodium is can be well combined with the drug molecules to form non-covalent complex, thereby enhancing the stability, water solubility, and safety of the drug, reducing its renal toxicity, easing drug hemolysis, controlling drug release rate, covering bad smell, etc. Compared with betacyclodextrin, sulfobutyl betacyclodextrin sodium has a higher water solubility, smaller hemolytic effect, and lower renal toxicity, which make it a new pharmaceutical excipient with very broad application prospects.

[Chemical Properties]

β-Cyclodextrin, sulfobutyl ethers, sodium salts is a cyclic oligosaccharide containing seven D-(t)- glucopyranose units attached by α(1→4) glucoside bonds. Sulfobutylether b-cyclodextrin is an anionic bcyclodextrin derivative with a sodium sulfonate salt separated from the hydrophobic cavity by a butyl spacer group. The substituent is introduced at positions 2, 3, and 6 in at least one of the glucopyranose units in the cyclodextrin structure. Introducing the sulfobutylether (SBE) into b-cyclodextrin can produce materials with different degrees of substitution, theoretically from 1 to 21; the hepta-substituted preparation (SBE7-b-CD) is the cyclodextrin with the most desirable drug carrier properties. Sulfobutylether b-cyclodextrin occurs as a white amorphous powder.
