As is typical of most higher-molecular weight alcohols, it is sparingly soluble in water at room temperature, but highly soluble in most common organic solvents.
Rosarin and rosavin are cinnamyl alcohol glycosides isolated from Rhodiola rosea. Cofactor recycling for selective enzymatic biotransformation of cinnamaldehyde to cinnamyl alcohol”.

Isopropyl alcohol is miscible in water, ethanol, and chloroform. It dissolves ethyl cellulose, polyvinyl butyral, many oils, alkaloids, gums and natural resins.
Isopropyl alcohol forms an azeotrope with water, which gives a boiling point of 80. Alcohol mixtures have depressed melting points. It has a slightly bitter taste, and is not safe to drink. Isopropyl alcohol can be oxidized to acetone, which is the corresponding ketone. Isopropyl alcohol is often used as both solvent and hydride source in the Meerwein-Ponndorf-Verley reduction and other transfer hydrogenation reactions.
