Carboxymethyl beta-cyclodextrin is a modified form of the naturally occurring compound beta-cyclodextrin, derived from starch. It is a versatile solubilizing and stabilizing agent widely used in pharmaceutical and food industries. Its ability to form inclusion complexes with various molecules enhances the solubility and bioavailability of poorly water-soluble drugs, while also improving the stability and controlled release of active ingredients in pharmaceutical formulations. In the food industry, it is utilized to mask undesirable flavors and odors, as well as to improve the stability and solubility of certain ingredients.

Uses
Used in Pharmaceutical Industry:Carboxymethyl beta-cyclodextrin is used as a solubilizing and stabilizing agent for poorly water-soluble drugs, improving their solubility and bioavailability. It forms inclusion complexes with these drugs, enhancing their stability and controlled release in pharmaceutical formulations.
Used in Food Industry:
Carboxymethyl beta-cyclodextrin is used as a flavor and odor masking agent to improve the taste and aroma of food products. It also serves as a stabilizing and solubility-enhancing agent for certain food ingredients, ensuring their uniform distribution and maintaining the quality of the final product.
Check Digit Verification of cas no
The CAS Registry Mumber 218269-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,2,6 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.Calculate Digit Verification of CAS Registry Number 218269-34:
(8*2)+(7*1)+(6*8)+(5*2)+(4*6)+(3*9)+(2*3)+(1*4)=142
142 % 10 = 2
So 218269-34-2 is a valid CAS Registry Number.
