Description

Lignoceric Acid CAS NO 557-59-5 is a saturated very-long-chain fatty acid, also known as tetracosanoic acid, which serves as a fundamental building block in lipid chemistry and biochemistry. This high-purity fatty acid is valued for its role in synthesizing specialized surfactants, lubricants, and as a critical standard in analytical research. It is essential for manufacturers and researchers in the cosmetics, pharmaceuticals, and specialty chemicals industries who require consistent, high-quality lipid components.

Application

• Biochemical Research & Standards: Used as a primary standard in gas chromatography (GC) and mass spectrometry (MS) for the analysis of complex lipids and fatty acid profiles.
• Cosmetic & Personal Care Formulations: Acts as a key intermediate in the production of emulsifiers, wax esters, and conditioners for skin and hair care products.
• Pharmaceutical Intermediates: Serves as a starting material for the synthesis of lipid-based drug delivery systems and bioactive compounds.
• Specialty Surfactants & Lubricants: Utilized in the manufacture of high-performance surfactants, corrosion inhibitors, and synthetic lubricants.
• Material Science: Employed in surface coatings and as a modifier for polymers to alter physical properties.
