Furoic acid, is the oldest know furan derivative

First described in 1780 by Carl Wilhelm Scheele, furoic acid is the first down-line oxidation derivative of furfural and a versatile starting material for the synthesis of pharmaceutical, agricultural and industrial chemicals. It is is frequently converted to furoyl chloride to be used in the production of drugs and insecticides. Furoic acid is also a feedstock for the production of Furan-2,5-dicarboxylic acid (FDCA), an important renewable building block, because it can substitute for terephthalic acid (PTA) in the production of polyesters.
