Suberic acid ( suberic acid, Oktandisäure ) is a dicarboxylic acid. As a dibasic acid suberic acid dissociates in water in two stages. The corresponding dissociation constants pKa1 = 4.51 and pKa2 amount = 5.40 in water at 25 ° C. Its salts and esters are called suberates; Ester of suberic acid may be used as plasticizers.
