China and the United States are the leading exporters of dimethyl phosphite (CAS 868-85-9), accounting for the largest shares of global supply, while India, South Korea, and Germany represent the top importing markets. Dimethyl phosphite prices have remained relatively stable amid steady cross-border flows, reflecting consistent industrial demand for use in agrochemical and pharmaceutical intermediates. Export volumes from China increased modestly in 2023–2024, while Indian imports rose by approximately 12% year-on-year, signaling growing downstream manufacturing activity.
Dimethyl phosphite is a colorless to pale yellow, volatile liquid with a faint, characteristic odor. It is an organophosphorus compound classified as a phosphite ester, with a boiling point of approximately 175–180 °C and moderate water solubility. It serves primarily as a key synthetic intermediate in the production of phosphorus-containing compounds, including flame retardants, pharmaceuticals, and agrochemicals. Its main industrial applications include the synthesis of phosphonates (e.g., glyphosate precursors), stabilizers for polymers and plastics, and catalysts or ligands in organic transformations. It is widely utilized in agrochemical and pharmaceutical manufacturing, as well as in specialty polymer and coating formulations.
