Description

Butyl Dihydrogen Phosphate is a versatile organophosphorus compound primarily used as an intermediate and catalyst in specialty chemical synthesis. Its value lies in its strong acidity and solubility in organic media, making it a key reagent for esterification and phosphorylation reactions. This product is essential for manufacturers in the agrochemical, pharmaceutical, and polymer industries seeking to develop advanced formulations and functional materials.

Application

• Agrochemical Intermediate: A key building block in the synthesis of organophosphate pesticides and herbicides.
• Pharmaceutical Synthesis: Used as a phosphorylating agent and catalyst in the production of active pharmaceutical ingredients (APIs).
• Polymer Additive & Catalyst: Functions as a flame retardant precursor and a catalyst in polymerization processes for resins and plastics.
• Metal Extraction & Separation: Employed as an extractant in hydrometallurgical processes for the recovery of rare earth and precious metals.
• Lubricant & Fuel Additive: Acts as an anti-wear agent and corrosion inhibitor in advanced lubricant and fuel formulations.
• Surface Treatment Agent: Used in coatings and surface modification to enhance adhesion and corrosion resistance.
