74996-30-8 Usage
General Description
Cholesteryl isoamyl ether is a chemical compound that is derived from cholesterol and isoamyl alcohol. It is mainly used as a chiral resolving agent in chromatography, particularly in the separation of enantiomers. CHOLESTERYL ISOAMYL ETHER is of interest in the pharmaceutical and chemical industries due to its ability to separate and purify different chiral compounds. Cholesteryl isoamyl ether is also used as a solvent in various chemical reactions and as a reagent in organic synthesis. It is a colorless, oily liquid with a faint odor, and it is considered to be relatively stable under normal conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 74996-30-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,9 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74996-30:
(7*7)+(6*4)+(5*9)+(4*9)+(3*6)+(2*3)+(1*0)=178
178 % 10 = 8
So 74996-30-8 is a valid CAS Registry Number.

The Synthesis of Cholesteryl Alkyl Ethers
Halperin, G.,Gatt, S.
, p. 39 - 42 (2007/10/02)
Seventeen cholesteryl alkyl ethers were synthesized through alcoholysis of cholesterol p-toluenesulfonate.This method was found superior to the etherification of sodium or potassium cholesterylate with alkyl halides or methanesulfonates, especially for the preparation of long-chain unsaturated alkyl ethers of cholesterol of high specific activity.
