Applications & Uses

Uses

5-(4-Chlorophenyl)-2-furoic acid (5-(4-chlorophenyl)-2-furancarboxylic acid) is a 5-aryl-2-furancarboxylic acid. It has been synthesized by oxidation of the corresponding furaldehyde with silver nitrate and sodium hydroxide. It serves as an intermediate for the synthesis of 5-(5-aryl-2-furyl)-tetrazol-1-ylacetic acids, which are employed in the synthesis of semisynthetic cephalosporines.
