Heptanoic Acid is an odourless, colourless liquid that is less dense than water and has a low water solubility. Vinyl plasticizers, which are used in the automobile sector, and synthetic lubricants, where it is employed in polyol esters, are the two main uses of heptanoic acid. As an organic building block, heptanoic acid is used in the production of numerous chemical compounds. It is generally used to prepare pharmaceutical chemicals like testosterone enanthate, drostanolone enanthate, and methenolone enanthate by esterifying steroids.

Moreover, it serves as an internal standard for the analysis of volatile acids using gas chromatography. Enanthic acid is another name for Heptanoic Acid. It is an organic molecule with a seven-carbon chain that ends in a functional carboxylic acid group. It is an oily, colourless liquid with a rotten stench. It helps some rancid oils smell better. Heptanoic acid has experienced a sharp increase in demand in recent years due to its application in the production of esters for the fragrance business, as a cigarette addition, and as a component of plant metabolites.
