The butyrate or butanoate ion, C 3 H 7 COO −, is the conjugate base of butyric acid. It is the form found in biological systems at physiological pH . A butyric (or butanoic) compound is a carboxylate salt or ester of butyric acid.
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. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:
Ethyl butyrate, also known as ethyl butanoate, or butyric ether, is an ester with the chemical formula CH 3 CH 2 CH 2 COOCH 2 CH 3. It is soluble in propylene glycol, paraffin oil, and kerosene. It has a fruity odor, similar to pineapple, and is a key ingredient used as a flavor enhancer in processed orange juices. [1]
Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid. Like most esters, it has a fruity odor, in this case resembling apples or pineapples. [2] At room temperature, it is a colorless liquid with low solubility in water, upon which it floats to form an oily layer.
For example, the ester hexyl octanoate, also known under the trivial name hexyl caprylate, has the formula CH 3 (CH 2) 6 CO 2 (CH 2) 5 CH 3. Butyl acetate, an ester derived from a residue of butanol (CH 3 CH 2 CH 2 CH 2 OH) (the butanol residue is butyl group −CH 2 CH 2 CH 2 CH 3) (right side of the picture, blue) and acetic acid CH 3 CO 2 H ...
Isovaleric acid, also known as 3-methylbutanoic acid or β-methylbutyric acid, is a branched-chain alkyl carboxylic acid with the chemical formula (CH 3) 2 CHCH 2 CO 2 H. It is classified as a short-chain fatty acid. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. The compound occurs naturally and can be found in ...
