Name: Betadex sulfobutyl ether sodium

CAS NO. : 182410-00-0

DMF No.: 030167

Sulfobutyl Ether-ß-cyclodextrin Sodium salt has been used in injection, oral, nasal and eye medication. Modification by charged functional units can improve the binding affinity of cyclodextrins for oppositely charged guests, so it has a special affinity for drugs with nitrogen elements.

Molecular Formula:C₄₂H_70-nO₃₅ (C₄H₈O₃S Na)n

Molecular Weight : 1135+158n
