Description

12-Octadecenoic Acid is a monounsaturated fatty acid with the CAS registry number 7378-88-3. This compound serves as a versatile intermediate and building block in the synthesis of specialty chemicals, surfactants, and lubricant additives. It is particularly valuable for research and industrial applications requiring a defined fatty acid structure with a single double bond, such as in polymer modification and the production of oleochemical derivatives.

Application

• Chemical Intermediate: A key raw material for synthesizing esters, amides, and other oleochemical derivatives.
• Surfactant & Detergent Production: Used in the manufacture of emulsifiers and soaps for industrial and cleaning formulations.
• Lubricant Additives: Acts as a precursor for bio-based lubricants and friction modifiers.
• Polymer Science: Employed in the modification of polymers and resins to alter physical properties.
• Research & Development: Serves as a standard or reagent in analytical chemistry and biochemical studies.
• Personal Care Ingredients: A potential component in the synthesis of emollients and conditioners for cosmetic products.
