Terebic acid, also known as terpene-4-carboxylic acid, is an organic compound found in the resin of coniferous trees. Due to its presence in these trees, it is commonly referred to as "coniferic acid." Other synonyms for terebic acid include (1R,2S,5R)-2-isopropenyl-5-methylcyclohexane-1-carboxylic acid, 2-Isopropenyl-5-methylcyclohexane-1-carboxylic acid, and p-carboxy-α,α,4-trimethylcyclohexene. Terebic acid has been studied for its potential use as an antimicrobial and antiviral agent, as well as for its ability to inhibit the growth of cancer cells. Its various synonyms are important to know for the purpose of research and academic discussion.
