Pentyl butyrate, also known as pentyl butanoate or amyl butyrate, is an ester that is formed when pentanol is reacted with butyric acid,[http://cameochemicals.noaa.gov/chemical/2470 N-AMYL BUTYRATE], Cameo Chemicals, National Oceanic and Atmospheric Administration usually in the presence of sulfuric acid as a catalyst. This ester has a smell reminiscent of pear or apricot. This chemical is used as an additive in cigarettes.
