Description

Oleic Anhydride is a high-purity chemical intermediate derived from oleic acid, serving as a versatile reagent for introducing oleoyl groups. Its primary value lies in enabling efficient acylation reactions, offering a more reactive alternative to oleic acid for ester and amide synthesis. This product is essential for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking to modify the properties of polymers, surfactants, and active ingredients. It is also a key building block in lubricant additive and plasticizer formulation.

Application

• Pharmaceutical Intermediates: Used in the synthesis of prodrugs and active pharmaceutical ingredients (APIs) requiring lipophilic oleoyl side chains.
• Cosmetic & Personal Care Ingredients: Acts as a key reactant in producing oleate esters for emollients, thickeners, and conditioning agents in creams and lotions.
• Polymer Modification: Employed as an acylating agent to functionalize polymers, improving flexibility, hydrophobicity, or biocompatibility.
• Lubricant & Grease Additives: A precursor for manufacturing metal oleates and other compounds that enhance lubricity and anti-wear properties.
• Plasticizer Synthesis: Serves as a starting material for creating specialized oleate-based plasticizers for PVC and other polymers.
• Surfactant Production: Utilized in the manufacture of anionic and nonionic surfactants for industrial and household cleaners.
• Research & Development: A valuable reagent in organic synthesis labs for exploring new chemical entities and material science applications.
• Textile Chemicals: Used in producing fabric softeners and water-repellent finishes for textiles.

Quality Control

Our Oleic Anhydride is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, acid value, and identification, to meet stringent specifications. Certificates of Analysis (COA) documenting all test results are provided with every shipment. We adhere to cGMP principles where applicable, ensuring reliability for critical applications in regulated industries.

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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent degradation by atmospheric moisture. Keep away from strong bases, strong oxidizing agents, and heat sources.
