Tridecylic acid, or tridecanoic acid, also reffred to as C13 fatty acid, is an organic compound with the formula CH₃(CH₂)₁₁CO₂H. It is a 13-carbon saturated fatty acid. It is a white solid.

Quick facts Names, Identifiers ...

It is an odd-chained saturated fatty acid (OCFA) found in human blood plasma. Thought, like other OCFAs in blood plasma, to originate mainly from rumen or gut-microbial lipogenesis, its metabolic role needs further study.^[8]

A laboratory preparation involves permanganate oxidation of 1-tetradecene (CH₃(CH₂)₁₂CH=CH₂).^[9]
