Erucic Acid, also known as 13-Docosenoic acid, is a very-long-chain monounsaturated fatty acid (VLCMUFA) with the chemical formula C22H42O2 and a molecular weight of 338.57. It is found naturally in various plant oils, such as rapeseed, mustard, and some animal fats like cod liver oil, with high concentrations in certain species like Crambe abyssinica。 This fatty acid is characterized by its hydrophobicity and excellent lubrication properties, which make it valuable across diverse industries including metallurgy, machinery, rubber, and chemicals.

Erucic Acid is used primarily as an intermediate in the production of fine chemicals, such as surface active agents, lubricants, plasticizers, emulsifiers, softeners, waterproofing agents, and detergents。 Its derivatives, such as erucamide, are utilized as slip agents in the manufacturing of plastic films like polyethylene. Additionally, it can be hydrogenated to produce behenic acid, which is used as a plasticizer, lubricant, and stabilizer in the plastic, pharmaceutical, and food industries。 Erucic Acid can also be oxidized to produce tridecanedioic acid and nonanoic acid, which are key materials for synthesizing nylon-13 and nylon-1313, and can be used in the creation of fragrances, musk, and low-temperature and light-resistant plasticizers.

Furthermore, high erucic oils are considered promising substrates for biofuel and biodiesel production due to their high energy potential. The acid's industrial significance is further underscored by its use in high-temperature lubricants, inks, and as a chemical raw material。 Its unique properties position Erucic Acid as a critical component in the development of environmentally safe and biodegradable oil products.
