Pentyl butyrate, also known as pentyl butanoate or amyl butyrate, is an ester that is formed when pentanol is reacted with butyric acid, [1] 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.
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).

Pentyl is a five-carbon alkyl group or substituent with chemical formula-C 5 H 11. It is the substituent form of the alkane pentane . In older literature, the common non-systematic name amyl was often used for the pentyl group.
Butyric acid was first observed in an impure form in 1814 by the French chemist Michel Eugène Chevreul.By 1818, he had purified it sufficiently to characterize it. However, Chevreul did not publish his early research on butyric acid; instead, he deposited his findings in manuscript form with the secretary of the Academy of Sciences in Paris,
Butyl butyrate, or butyl butanoate, is an organic compound that is an ester formed by the condensation of butyric acid and n-butanol. It is a clear, colorless liquid that is insoluble in water, but miscible with ethanol and diethyl ether. Its refractive index is 1.406 at 20 °C.
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane.
Amyl acetate (pentyl acetate) is an organic compound and an ester with the chemical formula CH 3 COO[CH 2] 4 CH 3 and the molecular weight 130.19 g/mol. It is colorless and has a scent similar to bananas [3] [4] and apples. [5] The compound is the condensation product of acetic acid and 1-pentanol.
