Pimelic acid (also heptanedioic or 1,5- pentanedicarboxylic ) belongs to the homologous series of dicarboxylic acids. It is in this between the adipic acid and suberic acid of ( suberic acid ). Its salts are called pimelates.

In contrast to the adipic acid pimelic acid is only a very limited range of applications in the chemical industry.

Properties

As a dibasic acid dissociates pimelic acid in water in two protolysis. Your octanol - water partition coefficient is log ( KOW ) = 0.61.
