Description

Neodecanoic Acid CAS NO 26896-20-8 is a highly branched, synthetic C10 monocarboxylic acid valued for its exceptional stability and resistance to oxidation. This unique structure provides superior performance in applications requiring high chemical and thermal resilience compared to linear carboxylic acids. It is a critical intermediate for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product durability and performance.

Application

• Polymer Industry: As a key monomer for producing high-performance vinyl ester resins and alkyd resins, improving flexibility and chemical resistance.
• Lubricant & Grease Manufacturing: Used in the synthesis of metal carboxylates (e.g., calcium, zinc soaps) that act as thickeners and stabilizers in lubricating greases.
• Corrosion Inhibitors: Serves as a precursor for oil-soluble corrosion inhibitors used in fuel and lubricant additive packages.
• Plasticizers & Stabilizers: Employed in the production of esters that function as plasticizers and heat stabilizers for PVC and other polymers.
• Specialty Surfactants: The branched chain structure is ideal for synthesizing surfactants with good solubility and low foam characteristics for industrial cleaners.
• Paint & Coating Driers: A raw material for metallic driers (e.g., cobalt, manganese neodecanoates) that accelerate the drying of paints and inks.
• Adhesives & Sealants: Imparts improved adhesion and weathering resistance in various adhesive and sealant formulations.

Quality Control

Our Neodecanoic Acid is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against rigorous internal specifications, which typically include assay, acid value, color, and moisture content. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and contamination.
