Description

Di-o-Tolyl Methylphosphonate is an organophosphorus compound with the CAS number 60146-72-7, functioning as a versatile chemical intermediate. Its value lies in its role as a key building block for synthesizing more complex phosphorus-containing molecules, which are critical in advanced material science and specialty chemistry. This product is essential for R&D chemists and manufacturers in the agrochemical, pharmaceutical, and polymer industries seeking to develop new active ingredients or functional additives.

Application

• Agrochemical Intermediate: A crucial precursor in the synthesis of organophosphate insecticides, herbicides, and plant growth regulators.
• Pharmaceutical Synthesis: Used as a building block for creating novel active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring phosphorus-based functional groups.
• Flame Retardant Precursor: Serves as a starting material for the production of phosphorus-based flame retardants used in plastics, textiles, and electronics.
• Ligand and Catalyst Development: Employed in organometallic chemistry to develop new phosphonate ligands for catalytic systems.
• Polymer Modification: Acts as a monomer or cross-linking agent to introduce phosphonate groups into polymer chains, enhancing properties like adhesion, flame resistance, or metal chelation.
• Extractant and Chelating Agent: Utilized in hydrometallurgy and analytical chemistry for the selective extraction and separation of metal ions.
