Product Description

Sulfobutyl Beta Cyclodextrin Sodium CAS 182410-00-0, also known as Sulfobutyl Beta Cyclodextrin Sodium (SBECD), is a highly water-soluble anionic cyclodextrin derivative developed for pharmaceutical excipient applications. Betadex Sulfobutyl Ether Sodium CAS No. 182410-00-0 is widely used as a solubilizer, wetting agent, chelating agent (complexing agent), and polyvalent masking agent in advanced drug formulations.

Betadex Sulfobutyl Ether Sodium CAS No. 182410-00-0 has been successfully applied in injectable, oral, nasal, and ophthalmic drug formulations. Sulfobutyl Beta Cyclodextrin Sodium shows strong inclusion capability and specific affinity toward nitrogen-containing drugs, effectively improving drug solubility, stability, and formulation safety through non-covalent complex formation.

In pharmaceutical applications, Betadex Sulfobutyl Ether Sodium CAS No. 182410-00-0 helps reduce renal toxicity, minimize hemolysis, control drug release rates, and mask unpleasant odors, making Sulfobutyl Beta Cyclodextrin Sodium especially suitable for parenteral formulations requiring high safety and performance.
