Description

Isononylalcohols CAS NO 68515-81-1 are a group of branched-chain nonyl alcohols, primarily consisting of isomers of nonanol, valued for their role as versatile chemical intermediates and plasticizer alcohols. Their molecular structure provides excellent solvency and compatibility, making them crucial for modifying the properties of polymers and other materials. This product is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable performance in their formulations.

Application

• Primary raw material for the production of DINP (Diisononyl Phthalate) and other phthalate-based plasticizers for PVC.
• Intermediate in the synthesis of lubricant additives, such as esters and antioxidants.
• Solvent and coalescing agent in paints, coatings, and inks.
• Precursor for the manufacture of nonionic surfactants and emulsifiers.
• Used in the production of adhesives and sealants to enhance flexibility and adhesion.
• Chemical intermediate for acrylate esters used in specialty polymers.
• Component in metalworking fluids and industrial cleaning formulations.
• Starting material for the synthesis of various flavor and fragrance ingredients.

Quality Control

Our Isononylalcohols are produced under a stringent quality management system to ensure batch-to-batch consistency and reliability for industrial applications. Quality is verified through comprehensive analytical testing including gas chromatography (GC) for composition and purity. A Certificate of Analysis (COA) detailing specific parameters is provided with each shipment to guarantee compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and prevent evaporation.
