Description

(Z)-19-Docosenoic Acid CAS NO 55833-27-7 is a high-purity, monounsaturated fatty acid characterized by its long 22-carbon chain and cis-configuration. This specific isomer is valued for its role as a key intermediate and building block in the synthesis of specialized oleochemicals and advanced materials. It is essential for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking consistent, high-quality raw materials for research and production.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring long-chain fatty acid moieties for enhanced bioavailability or targeted delivery.
• Cosmetic & Personal Care Formulations: Serves as an emollient and conditioning agent in high-end skincare products, lipsticks, and hair care formulations, providing smooth texture and moisture retention.
• Lubricant & Grease Additive: Acts as a friction modifier and corrosion inhibitor in the formulation of synthetic lubricants and high-performance greases for industrial applications.
• Polymer & Resin Modification: Employed as a monomer or plasticizer in the production of specialty polymers, coatings, and resins to improve flexibility and durability.
• Biochemical Research: A critical standard and reagent in lipidomics research, membrane studies, and the investigation of metabolic pathways involving very long-chain fatty acids.
• Surfactant & Detergent Synthesis: Used as a hydrophobic feedstock for manufacturing novel surfactants, emulsifiers, and cleaning agents with specific performance characteristics.

Quality Control

Our (Z)-19-Docosenoic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) detailing purity, isomer content, and impurity profiles is provided with every shipment to guarantee traceability and compliance for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen or argon) is strongly recommended to preserve product integrity.
