Description

20-Hydroxy Arachidic Acid CAS NO 62643-46-3 is a hydroxylated derivative of arachidic acid, a long-chain fatty acid, which introduces a reactive site for further chemical modification. This functionalization is critical for synthesizing specialized surfactants, lubricant additives, and pharmaceutical intermediates where precise molecular architecture is required. It is primarily sought by R&D chemists and process engineers in the specialty chemicals, personal care, and advanced materials sectors.

Application

• Surfactant & Emulsifier Synthesis: Serves as a key hydrophobic building block for producing non-ionic surfactants with specific hydrophilic-lipophilic balance (HLB) values.
• Lubricant & Grease Formulation: Used to create synthetic esters that enhance the thermal stability and lubricity of high-performance industrial and automotive lubricants.
• Pharmaceutical Intermediates: Acts as a precursor in the synthesis of bioactive molecules and prodrugs due to its fatty acid backbone and modifiable hydroxyl group.
• Personal Care Ingredients: Incorporated into the production of emollients, wax esters, and viscosity modifiers for creams, lotions, and cosmetic formulations.
• Polymer Additives: Utilized to manufacture plasticizers and stabilizers that improve the flexibility and durability of polymers.
• Research & Development: A valuable standard and reagent in lipidomics research and for studying fatty acid metabolism and signaling pathways.

Quality Control

Every batch of 20-Hydroxy Arachidic Acid is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards through rigorous analytical protocols, including chromatography and spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

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). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed after each use to minimize exposure to moisture and air. For long-term storage, consider using an inert atmosphere (e.g., nitrogen or argon blanket).
