Products Description of Formic acid CAS#64-18-6 Formic acid is an important chemical raw material. It was first discovered by Fisher in 1670. A.S.Marggret first produced pure formic acid in 1749.It was first discovered by distilling red ants, hence the name formic acid. Formic acid is widely found in nature, such as in the secretions of red ants, bees, caterpillars, etc., in the leaves and roots of plants, and in fruits. It is the simplest carboxylic acid. Compared with other fatty carboxylic acids, it has a special structure and is more acidic.
