Description

Undecenoic Acid is a versatile medium-chain fatty acid characterized by a terminal double bond, making it a valuable building block in organic synthesis. This unique structure provides high reactivity for derivatization, enabling the production of a wide range of specialty chemicals and intermediates. It is essential for manufacturers in the fragrance, pharmaceutical, and polymer industries seeking to create high-value, functional end-products.

Application

• Fragrance and Flavor Intermediates: A key starting material for the synthesis of musk aromatics (e.g., ethylene brassylate) and other fragrance compounds.
• Pharmaceutical Synthesis: Used as a precursor in the manufacture of antifungal agents and other active pharmaceutical ingredients (APIs).
• Polymer and Resin Modifiers: Serves as a monomer or co-monomer to introduce flexibility, hydrophobicity, or specific functional groups into polymers.
• Lubricant and Grease Additives: Employed in the production of synthetic esters that enhance the performance of industrial lubricants.
• Surfactants and Emulsifiers: Acts as a raw material for creating anionic and nonionic surfactants for personal care and industrial formulations.
• Chemical Intermediate: Utilized in organic synthesis for chain extension, cyclization reactions, and the production of amides, esters, and salts.

Quality Control

Our Undecenoic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical processes.

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 oxidizing agents. Recommended storage temperature is 15-25°C. The container should be kept tightly sealed when not in use to minimize exposure to air.
