Betadex sulfobutyl ether sodium USP standard, Pharmaceutical Grade Excipient CAS#182410-00-0

Betadex sulfobutyl ether sodium USP standard, Pharmaceutical Grade Excipient,CAS#182410-00-0 

Betadex sulfobutyl ether sodium is a new type of anionic high soluble cyclodextrin derivatives. It could include drug molecules to from covalent compounds so that increase the drug's stability, solubility, safety. It could reduce the renal toxicity, moderate drug's hemolysis, control the release rate and cover up the bad smell.
