Description

Arachidic Acid Ethyl Ester is a high-purity fatty acid ester derived from arachidic acid, a long-chain saturated fatty acid. This compound serves as a critical intermediate and reference standard in advanced chemical synthesis and analytical applications. It is essential for industries requiring precise lipid components, such as pharmaceuticals, cosmetics, and specialty chemical manufacturing.

Application

• Pharmaceutical Intermediate: Used in the synthesis of lipid-based drug delivery systems, prodrugs, and active pharmaceutical ingredients (APIs).
• Reference Standard: Serves as a certified reference material (CRM) for gas chromatography (GC) and high-performance liquid chromatography (HPLC) in analytical laboratories.
• Cosmetic & Personal Care Ingredient: Acts as an emollient and texture enhancer in high-end skincare formulations, creams, and lotions.
• Biochemical Research: Employed in lipidomics research, membrane studies, and as a substrate for enzymatic studies involving lipases and esterases.
• Lubricant & Plasticizer Precursor: Used in the production of specialty synthetic lubricants and as a precursor for polymer plasticizers.
• Flavor & Fragrance Industry: Functions as a base material for synthesizing specific ester-based aroma compounds.
