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]
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).
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 .
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.
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 .
Isobutyric acid, also known as 2-methylpropanoic acid or isobutanoic acid, is a carboxylic acid with structural formula (CH 3) 2 CHCOOH.It is an isomer of butyric acid.It is classified as a short-chain fatty acid.
n-Butyl acetate is an organic compound with the formula CH 3 CO 2 (CH 2) 3 CH 3.A colorless, flammable liquid, it is the ester derived from n-butanol and acetic acid.It is found in many types of fruit, where it imparts characteristic flavors and has a sweet smell of banana or apple.
