<4α-2H>-Cholesterol, also known as deuterium-labeled cholesterol, is a chemical compound that is structurally similar to the naturally occurring cholesterol found in the human body. It is characterized by the presence of deuterium atoms (hydrogen isotopes) at specific positions in the molecule, which can be used for various scientific and medical purposes, such as studying cholesterol metabolism, drug interactions, and the development of new therapeutic agents. This labeled cholesterol can be synthesized through chemical reactions and is often used in research to trace the movement and metabolism of cholesterol in living organisms, providing valuable insights into its role in health and disease.

3915-25-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3915-25-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3915-25:
(6*3)+(5*9)+(4*1)+(3*5)+(2*2)+(1*5)=91
91 % 10 = 1
So 3915-25-1 is a valid CAS Registry Number.

A convenient and highly stereoselective synthesis of 4α-deuterio and -tritio steroids catalyzed by Pd

Rabinowitz

, p. 6081 - 6084 (2007/10/02)

A simple and highly stereoselective synthesis of [4α-2H]- and [4α-3H]-Δ5-3β-hydroxysteroids is presented. Palladium(O)-mediated borodeuteride reduction of readily-available cholest-5-en-3β,4β-diol cyclic carbonate provides [4α-2H]-Δ5-and Δ4-cholesterol in a 12:1 ratio. Reduction of [4α-3H]-cholest-5-ene-3β,4β-diol cyclic carbonate with NaB1H4 and Pd(O) resulted in [4β-3H]-cholesterol.
