Description

Hexadecenoic Acid CAS NO 25447-95-4 is a monounsaturated fatty acid, specifically a C16:1 fatty acid, which serves as a versatile intermediate and functional ingredient in advanced chemical synthesis. Its value lies in its unique carbon chain length and olefinic bond, which are critical for modifying the properties of polymers, surfactants, and personal care formulations. This high-purity chemical is essential for manufacturers and R&D teams in the pharmaceutical, cosmetics, and specialty chemicals industries seeking to develop innovative products with enhanced performance characteristics.

Application

• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, where its fatty acid structure can improve bioavailability.
• Cosmetics & Personal Care: Acts as an emollient and conditioning agent in creams, lotions, and hair care products, providing smooth texture and skin barrier support.
• Lubricant & Grease Additives: Serves as a precursor for synthetic esters used in high-performance biodegradable lubricants and metalworking fluids.
• Surfactant & Detergent Manufacturing: A key raw material for producing anionic and nonionic surfactants, offering excellent cleansing and foaming properties.
• Polymer Modification: Employed to create plasticizers and co-monomers for resins, enhancing flexibility and durability in finished polymers.
• Research & Development: A valuable standard and building block in biochemical and nutritional studies focused on lipid metabolism.

Quality Control

Our Hexadecenoic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure it meets the high-purity standards required for sensitive applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its nature of being easily oxidized, prolonged exposure to air and high temperatures should be avoided to maintain product integrity.
