Equisetolic acid or triacontanedioic acid is a chemical compound with the chemical formula HOOC—(CH₂)₂₈—COOH.^[1]^[2] The compound is a long-chain dicarboxylic acid, one of the longest naturally occurring dicarboxylic acids. It has been found in the spores and cones of Equisetum arvense and Equisetum telmateia.^[3]^[4]^[5]

Physical properties

Like other long-chain dicarboxylic acids, it demonstrates physical properties typical of fatty acids with extended carbon backbones, including high melting points^[6] and limited water solubility.
