Description

O,o-Dibutyl Hydrogen Thiophosphate is an organophosphorus compound primarily used as a versatile intermediate and reagent in chemical synthesis. Its value lies in its role as a key building block for creating more complex phosphorus-containing molecules, such as pesticides, flame retardants, and lubricant additives. This product is essential for manufacturers and R&D facilities in the agrochemical, specialty chemical, and polymer industries seeking reliable, high-purity intermediates for their processes.

Application

• Agrochemical Intermediate: A key precursor in the synthesis of organophosphate insecticides and herbicides.
• Flame Retardant Synthon: Used in the production of phosphorus-based flame retardants for plastics and polymers.
• Lubricant & Fuel Additive Component: Serves as an intermediate for anti-wear and extreme pressure additives.
• Chemical Synthesis Reagent: Employed in organic synthesis for the introduction of thiophosphate groups.
• Metal Extraction & Chelation: Acts as an extractant or chelating agent in hydrometallurgical processes for certain metals.
• Polymer Modification: Used to modify polymer chains to impart specific properties like adhesion or flame resistance.

Quality Control

Our O,o-Dibutyl Hydrogen Thiophosphate is manufactured under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including assay (by titration or GC), identity confirmation (IR), and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Due to its nature as a strong acid/organic solvent, handle with appropriate personal protective equipment and ensure containers are kept tightly sealed when not in use.
