Description

2-Ethyldecanoic Acid is a branched-chain fatty acid derivative, also known as 2-ethylcapric acid, valued for its role as a versatile chemical intermediate and building block. Its unique structure, featuring an ethyl branch on the alpha carbon, imparts distinct physical and chemical properties useful in advanced synthesis. This product is essential for manufacturers in the lubricant, plasticizer, and specialty chemical industries seeking to develop high-performance formulations.

Application

• Lubricant & Grease Additive: Used as a precursor for synthetic esters that serve as high-performance base oils and additives, offering excellent thermal stability and low-temperature fluidity.
• Plasticizer Intermediate: Acts as a key raw material in the production of specialized plasticizers for polymers like PVC, enhancing flexibility and durability.
• Corrosion Inhibitor Formulation: Employed in the synthesis of compounds that protect metal surfaces in industrial fluids and coatings.
• Specialty Surfactant Production: Serves as a hydrophobic feedstock for creating surfactants with specific branching for enhanced surface activity.
• Pharmaceutical & Agrochemical Intermediates: Utilized in organic synthesis to construct complex molecules for active ingredients.
• Flavor & Fragrance Ingredient: Used in the manufacture of esters that contribute to specific aroma profiles.
• Research & Development: A valuable reagent in chemical research for studying branched fatty acid behavior and synthesizing novel compounds.

Quality Control

Our 2-Ethyldecanoic Acid is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and consistency. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Recommended storage temperature: 15-25°C.
