Product Name:Erucic Acid
English Name:Erucic Acid
CAS No.:112-86-7
Aliases:cis-13-Docosenoic acid, (Z)-Docos-13-enoic acid, Docosenoic acid
Molecular Formula:C22H42O2
Physical Properties:White crystalline needles or powder. Molecular weight: 338.57. Insoluble in water; soluble in ethanol, ether, chloroform and other organic solvents. Melting point approx. 33–35 °C, boiling point approx. 358 °C (760 mmHg), relative density 0.853 g/cm³ (60 °C), flash point approx. 110 °C (closed cup). Naturally present in rapeseed oil and mustard oil.
Uses:Erucic acid is a long-chain monounsaturated fatty acid primarily used to produce erucamide, erucate esters and other derivatives. It is widely applied as a lubricant, anti-caking agent, surfactant, plastics processing additive, and cosmetic ingredient. It is also used to synthesize high-performance materials such as nylon 1313 and serve as a pharmaceutical intermediate.
