Description

Palmitoleic Acid Ethyl Ester is a high-purity fatty acid ester derived from palmitoleic acid, a monounsaturated ω-7 fatty acid. This compound serves as a versatile and valuable chemical intermediate and reference standard for research and industrial synthesis. It is essential for manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, cosmetic, and specialty chemical sectors seeking consistent, high-quality lipid components.

Application

• Pharmaceutical Intermediate: Used in the synthesis of bioactive molecules, prodrugs, and lipid-based drug delivery systems.
• Nutraceutical & Dietary Supplement Research: Acts as a key reference standard and precursor in the study of ω-7 fatty acid benefits.
• Cosmetic & Personal Care Formulations: Employed as an emollient and skin-conditioning agent in high-end skincare products.
• Biochemical Research: Serves as a substrate or standard in lipid metabolism, enzymology, and cell signaling studies.
• Flavor & Fragrance Industry: Utilized as a building block for synthesizing specific ester notes.
• Lubricant & Plasticizer Additive: Functions as a bio-based component in specialty lubricants and polymer formulations.
• Analytical Chemistry: Used as a certified reference material (CRM) for gas chromatography (GC) and mass spectrometry (MS) calibration.
