CAS 481-21-0: 5α-Cholestane
Description:5α-Cholestane, with the CAS number 481-21-0, is a saturated sterol and a derivative of cholesterol. It is characterized by a rigid, multi-ring structure typical of steroid compounds, featuring a total of 27 carbon atoms and a molecular formula of C27H46. This compound is notable for its lack of double bonds, which distinguishes it from its unsaturated counterparts. 5α-Cholestane is typically found in various biological systems and can be derived from the hydrogenation of cholesterol. It is insoluble in water but soluble in organic solvents, reflecting its hydrophobic nature. The compound is often used in biochemical research and as a reference standard in analytical chemistry, particularly in studies involving sterols and lipid metabolism. Its stability and structural integrity make it a valuable substance for understanding the behavior of sterols in biological systems. Additionally, 5α-Cholestane can serve as a biomarker for certain geological and biological processes, contributing to the study of ancient organisms and environmental conditions.
