Dimethyl Phosphite

Dimethyl Phosphite (CAS 868-85-9 ), commonly abbreviated as DMP, is a reactive organophosphorus ester used as a chemical intermediate and stabilizer across multiple industrial sectors. It functions primarily as a building block in the synthesis of phosphonate compounds. In agrochemical manufacturing, DMP serves as a key intermediate in producing organophosphate and phosphonate pesticides, herbicides, and fungicides. Polymer and plastics producers incorporate it as an antioxidant stabilizer in PVC and polyolefin formulations. The compound acts as an effective stabilizer where it inhibits thermal degradation during processing. Pharmaceutical manufacturers use DMP as a synthetic intermediate for active pharmaceutical ingredients, particularly in phosphonate-based drug synthesis. In water treatment chemistry, it contributes to the production of scale inhibitors and corrosion control agents applied in industrial cooling and boiler systems. This versatility makes it a critical component for various chemical processes. Dimethyl Phosphite is supplied as a colorless to pale yellow liquid in standard commercial packaging ranging from drums to ISO tank containers. Technical grade is the most common supply form for industrial and synthesis applications. Purity levels are typically at 98% or higher to ensure consistent performance in manufacturing. Pharmaceutical-intermediate grade material with tighter purity specifications is available for regulated manufacturing environments. Contact us for supply of Dimethyl Phosphite Request Quote
