Applications of 5-Amino-1-pentanol

5-Amino-1-pentanol is a soluble white crystal that must be stored in a tight container and placed in a cool, dry place. 5-Amino-1-pentanol is toxic and prone to burns, avoids direct contact, does not come into contact with oxidants, acids, air and carbon dioxide, and is present in mainstream smoke.

5-Amino-1-pentanol(5-AP) is an aliphatic amino alcohol with potential plasma lipid-lowering properties. 5-Amino-1-pentanol and other amino alcohols are used as emulsifying agents in dry-cleaning soaps, wax removers, cosmetics, paints and insecticides. 5-Amino-1-pentanol undergoes facile intramolecular cyclocondensation to piperidine and to methyl or ethyl piperidines in the presence of methanol or ethanol over zeolite catalysts like ZSM5 (Si/A1 = 30, 129, 280), HM and HY. 2-Aminopyran (2-AP) is also observed as a major product in the conversion of 5-Amino-1-pentanol to piperidine on the ZSM-5 (280) and HY. Piperidine and N-methylpiperidine are predominantly formed over HY zeolite with near total conversion (98%) of 5-Amino-1-pentanol in the 5-Amino-1-pentanol alkylation with methanol. 2-Methyl piperidine is also formed as a side product in this reaction over all the zeolites studied. Methanol conversion does not show any trend. 5-amino- 1 -pentanol has been shown to be an effective process for the preparation of saturated pyridine bases over zeolite catalysts.The selectivity to piperidine and 2-aminopyran depends on the type of zeolite used. 350℃ is the best temperature for the maximum conversion of 5-Amino-1-pentanol and high yield of piperidine and N-methylpiperidine on the various zeolites employed in the reaction[1]. 

5-Amino-1-pentanol can be used as a saccharification and amination intermediate for many drugs due to both hydroxyl and amino groups, and more and more are used in the synthesis of anticancer drugs and antiinflammatory drugs. 5-Amino-1-pentanol has a wide range of applications in drug modification and drug screening. 5-Amino-1-pentanol is the starting material for the synthesis of alkaloid manzamine. 5-Amino-1-pentanol has been used in the synthesis of S-glycosyl amino-acid building blocks. It has been used as starting reagent in the synthesis of aminofunctionalized 4-chloro-2,2′:6′,2′′-terpyridine.
