64691-57-2 Usage
General Description
Cyclodextrin-benzaldehyde is a chemical compound formed by the union of cyclodextrin, a cyclic oligosaccharide, with benzaldehyde, an organic compound commonly used in fragrances and flavorings. This complex has been studied for its potential as a drug delivery system due to the ability of cyclodextrin to encapsulate hydrophobic molecules like benzaldehyde. The inclusion of benzaldehyde also imparts unique properties to cyclodextrin, such as enhanced solubility, stability, and bioavailability of the encapsulated drug. As a result, cyclodextrin-benzaldehyde has shown promise in pharmaceutical applications as a carrier for improving the delivery and effectiveness of various drugs.
Check Digit Verification of cas no
The CAS Registry Mumber 64691-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,9 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 64691-57:
(7*6)+(6*4)+(5*6)+(4*9)+(3*1)+(2*5)+(1*7)=152
152 % 10 = 2
So 64691-57-2 is a valid CAS Registry Number.

An effective procedure for the synthesis of α-hydroxyphenylacetic acid with cyclodextrin (CD) catalysts was developed. The phase-transfer catalyst types, catalyst loadings, reaction times, reaction temperatures, and substrate molar ratios were investigated to optimize the reaction conditions. In addition, the factors that affect the reaction were studied, and the relationship between benzaldehyde and β-cyclodextrin (β-CD) was analyzed through 2D-ROESY. The equilibrium constant when β-CD was used as the catalyst was calculated. The results indicated that β-CD is the optimal catalyst for the reported reaction (yield: 69.08%). Furthermore, the mechanism underlying the reported reaction was proposed.
