Description

Isononyl Dihydrogen Phosphate is an organophosphorus compound widely used as an intermediate and functional additive. This product is valued for its role in synthesizing specialized surfactants, lubricant additives, and metal extraction agents. It serves critical functions in the chemical manufacturing, lubricants, and metal processing industries, where its specific phosphate ester chemistry is required.

Application

• Surfactant & Detergent Intermediate: A key raw material for the synthesis of anionic surfactants and phosphate ester surfactants used in industrial and institutional cleaning formulations.
• Lubricant & Anti-Wear Additive: Functions as a precursor for anti-wear and extreme pressure (EP) additives in metalworking fluids, hydraulic oils, and gear lubricants.
• Metal Extraction & Separation Agent: Employed in hydrometallurgical processes for the solvent extraction and purification of various metals, including rare earth elements.
• Polymerization Modifier & Catalyst: Acts as a co-catalyst or modifier in certain polymerization reactions to control molecular weight and polymer architecture.
• Flame Retardant Synergist: Used as a component in flame-retardant systems for plastics and textiles, often in combination with other agents.
• Corrosion Inhibitor Formulation: Serves as a building block for formulating corrosion inhibitors used in water treatment and industrial cooling systems.

Quality Control

Our Isononyl Dihydrogen Phosphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and moisture content 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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
