Description

Dodecyl Dihydrogen Phosphate is a versatile organophosphorus compound widely used as an intermediate, surfactant, and extractant. Its amphiphilic structure, featuring a long alkyl chain and a phosphate head group, provides excellent surface-active and chelating properties critical for numerous industrial processes. This chemical is essential for manufacturers in the agrochemical, lubricant, and metalworking industries, where it serves as a key building block for specialty chemicals and functional additives.

Application

• Agrochemical Intermediates: A key precursor in the synthesis of organophosphate pesticides and herbicides.
• Lubricant & Fuel Additives: Functions as an anti-wear agent, corrosion inhibitor, and detergent in industrial lubricants and fuel formulations.
• Metal Extraction & Surface Treatment: Used as a solvent extractant for rare earth and precious metals, and in metal cleaning and phosphating processes.
• Emulsion Polymerization: Acts as an anionic surfactant and stabilizer in the production of polymers like PVC and acrylics.
• Personal Care & Detergents: Employed as a mild surfactant and emulsifying agent in specialized cosmetic and cleaning products.
• Pharmaceutical Synthesis: Serves as an intermediate in the production of certain active pharmaceutical ingredients (APIs).
