Heptatriacontanoic acid, or heptatriacontylic acid, is a 37-carbon saturated fatty acid.


Heptatriacontanoic acid is present in Abelmoschus manihot and Alpinia nigra.[1][2] Heptatriacontanoic acid was also measured in zooplankton.[3]


The compound 4,21-dimethyl-5,19-di-(trans)-enoyl-heptatriacontanoic acid is the "structure of the major homolog of free mycobacteric acids" of Mycobacterium brumae.[4]


The expired U.S. patent 5502226 covers a method of ω-hydroxy acid preparation that includes heptatriacontanoic acid.[5]
