Butanoic acid also called butyric acid is a carboxylic acid with the chemical formula C4H8O2. Visit BYJU'S to understand the properties, structure and uses of butanoic acid.

Carboxylic acids feature a carbon atom doubly bonded to an oxygen atom and also joined to an OH group. The four acids illustrated here are formic acid (a), acetic acid (b), propionic acid (c), and butyric acid (d). The acid with the carboxyl group attached directly to a benzene ring is called benzoic acid (C 6 H 5 COOH).

Butyric acid (/ ˈbjuːtɪrɪk /; from Ancient Greek: βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula CH3CH2CH2COOH. It is an oily, colorless liquid with an unpleasant odor. Isobutyric acid (2-methylpropanoic acid) is an isomer.

Butanoic acid is an oily and colourless liquid having the chemical formula CH 3 CH 2 CH 2-COOH. It is a type of short-chain saturated fatty acid, which is found in the form of esters in plant oils and animal fats.
