General Description
Cholesteryl carbonate is a chemical compound belonging to the class of cholesteryl esters, which are derivatives of cholesterol. It is a carbonate ester formed by the reaction of cholesterol with carbonic acid. Cholesteryl carbonate has found applications in various fields, including pharmaceuticals, cosmetics, and the food industry, due to its ability to form stable emulsions and its potential as a drug delivery system. It is also being studied for its potential use in the development of new materials and biomaterials. Cholesteryl carbonate is considered to be a biocompatible compound and has shown promising properties for use in the medical and biotechnological fields.
Check Digit Verification of cas no
The CAS Registry Mumber 29331-39-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,3,3 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29331-39:
(7*2)+(6*9)+(5*3)+(4*3)+(3*1)+(2*3)+(1*9)=113
113 % 10 = 3
So 29331-39-3 is a valid CAS Registry Number.

Physicochemical properties and antifungal activity of amphotericin b incorporated in cholesteryl carbonate esters
Chuealee, Rabkwan,Wiedmann, Timothy Scott,Srichana, Teerapol
, p. 1727 - 1735 (2013/01/10)
The antifungal activity of amphotericin B (AmB) incorporated in three cholesteryl carbonate esters (CCEs), sodium cholesteryl carbonate, cholesteryl palmityl carbonate, and dicholesteryl carbonate, was examined to assess their potential for use in a dry powder aerosol. Formulations containing dissolved AmB were stable for 6 months. The particle size varied inversely with liquid crystalline content with observed mass median aerodynamic diameters ranging from 4 to 8 μm. This was consistent with the visual appearance of the liquid crystals as being low density and free flowing at room temperature. When dispersed in water, the presence of the CCE reduced the rate and extent of AmB release, consistent with the estimated liquid crystal/water partition coefficient. Nevertheless, the rate of AmB release was always sufficient to kill the fungus as established with bioactivity studies. AmB formulated with CCE as a dry powder appears to be promising for use in treating lung fungal infections.
