13-Methyltetradecanoic acid, also known as isopentadecanoic acid (or iso-C15:0), is a 15-carbon branched-chain saturated fatty acid with the chemical formula C15H30O2 and a molecular weight of 242.4 g/mol. Isopentadecanoic acid is classified as a long-chain fatty acid, a branched-chain saturated fatty acid, and a methyl-branched fatty acid.
Isopentadecanoic acid has been shown to induce apoptotic cell death and inhibition of tumor growth in human bladder cancer cells. For these reasons, it has been considered a potential chemotherapeutic supplement.
