Product Name:Lithocholic acid
English Name:Lithocholic acid
CAS No.:434-13-9
Aliases:3α-Hydroxy-5β-cholan-24-oic acid, 5β-Cholanic acid-3α-ol
Molecular Formula:C24H40O3
Physical Properties:White to off-white crystalline powder, odorless with a bitter taste. Freely soluble in ethanol, acetone, diethyl ether and glacial acetic acid; slightly soluble in chloroform; practically insoluble in water. Melting point 184–187 °C; specific rotation [α]D20 +32° to +35° (c = 1, ethanol).
Uses:Lithocholic acid is a secondary bile acid formed by bacterial biotransformation of cholesterol in the intestine. It is used in the pharmaceutical industry as an intermediate for the synthesis of steroidal drugs and other bile acid derivatives. In biochemical research, it is widely used in experimental studies on bile acid metabolism and lipid digestion/absorption mechanisms.
Technical Specifications:
Purity: ≥99%
Molecular weight: 376.57
Melting point: 184–187 °C
Loss on drying: ≤0.5%
Residue on ignition: ≤0.1%
