Chemical compound

Amyl acetate (pentyl acetate) is anorganic compound and anester with the chemical formula CH3COO[CH2]4CH3 and the molecular weight 130.19 g/mol. It is colorless and has ascent similar tobananas[3][4] andapples.[5] The compound is the condensation product ofacetic acid and1-pentanol. However, esters formed from other pentanol isomers (amyl alcohols), or mixtures of pentanols, are often referred to as amyl acetate. The symptoms of exposure to amyl acetate in humans aredermatitis,central nervous system depression,narcosis and irritation to the eyes and nose.[3]

Uses

[edit]

Amyl acetate is a solvent for paints, lacquers, andliquid bandages;[6] and aflavorant. It also fuels theHefner lamp andfermentative productions ofpenicillin.
