Quality Advantage Of Betadex Sulfobutyl Ether Sodium From Zhiyuan Biotechnology

- Jan 22, 2018 -

Zhiyuan Biotechnology is the largest manufacturer of Pharmaceutical Excipients in China.

Specialized in the production of Sulfobutyl ether-beta-cyclodextrin sodium salt.Our Sulfobutyl ether-beta-cyclodextrin sodium salt has obtained DMF No.: 030167.


Our cyclodextrin technology is in cooperation with Shandong University which is the most professional study of cyclodextrin. Quality advantage of Betadex Sulfobutyl Ether Sodium mainly manifested in the color of the product, turbidity, solution clarification, impurity, substitution degree as below:


●  Betadex Sulfobutyl Ether Sodium clarity of solution is very clear, without peculiar smell, it is better than other companies.


  The impurity content is lower, it's almost zero, not more than 0.1%,and it can meet USP40-NF35 standard.


  We can control the indexes of 1,4-butane sultone, 4-Hydroxybutane-1-Sulfonic Acid are both very lower, content of Disodium bis-(4-sulfobtyl) ether is absence.


  In fact,the degree of substitution which from 6.2 to 6.9 has already meet USP40-NF35 Standard,but we also can accurately control the degree of substitution between 6.4-6.6.
