Copalic acid is a chemical compound that is a constituent of copaiba oil, an oleoresin extracted from trees in the genus Copaifera.

[1] It is a diterpenoid of the labdane class.

[2] Because copaiba oil has some uses in traditional herbal medicine, there has been scientific interest in investigating the potential pharmacology of its constituents, including copalic acid.

[2][3] In addition, synthetic derivatives of copalic acid have been investigated for their potential pharmacology as well.

[4] Several laboratory syntheses of copalic acid have been reported.
