    Product Description

    Heptacosanoic acid is an odd-chain saturated fatty acid. It has been used as an internal standard for the quantification of very long-chain fatty acids (VLCFAs) in human serum.1 Heptacosanoic acid has been found in wood smoke, as well as in urban and rural emissions of fine particulate matter less than 2.5 µm in aerodynamic diameter (PM2.5).2,3

    WARNING This product is not for human or veterinary use.
