Description

12-Hydroxy-9-Octadecynoic Acid is a unique fatty acid derivative characterized by the presence of both a hydroxyl group and a triple bond in its carbon chain. This bifunctional structure makes it a valuable intermediate for synthesizing specialized polymers, lubricant additives, and surface-active agents. It is particularly relevant for manufacturers in the chemical synthesis, specialty materials, and industrial additive sectors seeking to introduce specific functional groups into their products.

Application

• Chemical Intermediate: A key building block for the synthesis of complex organic molecules, including specialty esters and amides.
• Polymer Modification: Used to introduce hydroxyl functionality into polymers, improving adhesion, cross-linking potential, and compatibility.
• Lubricant & Grease Formulation: Serves as a precursor for high-performance additives that enhance thermal stability and reduce friction.
• Surfactant & Detergent Production: The polar head group and long hydrocarbon tail make it suitable for creating non-ionic surfactants.
• Corrosion Inhibitor Synthesis: Used in formulating compounds that protect metal surfaces in industrial fluids.
• Research & Development: Employed in academic and industrial R&D for studying fatty acid chemistry and developing new materials.

Quality Control

Our 12-Hydroxy-9-Octadecynoic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay, impurities, and physical parameters are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture. Keep away from strong acids and incompatible organic solvents.
