Products 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.
Compared with betacyclodextrin, sulfobutyl betacyclodextrin sodium has a higher water solubility, smaller hemolytic effect, and lower renal toxicity, which make it a new excipient with very broad application prospects.
