Common NamePentyl 2-furyl ketone
DescriptionPentyl 2-furyl ketone, also known as 1-(2-furanyl)-1-hexanone or 2-furyl N-pentyl ketone, belongs to the class of organic compounds known as aryl alkyl ketones. These are ketones have the generic structure RC(=O)R', where R = aryl group and R'=alkyl group. Pentyl 2-furyl ketone is an extremely weak basic (essentially neutral) compound (based on its pKa). Pentyl 2-furyl ketone is a sweet, apricot, and fruity tasting compound. Outside of the human body,.
