Product Application Of 1-Pentanol CAS#71-41-0
Raw material for pharmaceutical preparations;organic synthesis solvent.
1-Pentanol is used as a key starting material in the production of dichloro-acetic acid pentyl ester, 2-methyltetrahydrofuran, di-n-penyl ether (DNPE), pentyl butyrate and amyl acetate. As a solvent, it is used for coating CDs and DVDs. It has been considered to be a replacement for gasoline and diesel fuels due to its combustion properties. Further, it is used as a reagent to prepare derivatives of ferulic acid and caffeic acid, which shows anticancer properties.
