Description

Diethyl Chlorothiophosphate is a key organophosphorus intermediate with significant utility in synthetic chemistry. This compound matters for its role as a versatile building block in the production of more complex molecules, particularly in the agrochemical and pharmaceutical sectors. Industries that require the synthesis of pesticides, insecticides, or specialized chemical reagents will find this high-purity intermediate essential for their manufacturing processes.

Application

• Agrochemical Intermediate: Primary use in the synthesis of organophosphate insecticides and pesticides.
• Pharmaceutical Synthesis: Serves as a key reagent in the production of certain active pharmaceutical ingredients (APIs).
• Chemical Research: Utilized in laboratories for the development of novel organophosphorus compounds.
• Flame Retardant Production: Acts as a precursor in the manufacture of certain flame-retardant additives.
• Lubricant Additive Synthesis: Used in the creation of extreme-pressure additives and anti-wear agents.
• Polymer Modification: Employed to introduce thiophosphate groups into polymer chains for specialized material properties.

Quality Control

Our Diethyl Chlorothiophosphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available for all commercial shipments to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature and strong acid/organic solvent properties, the container must be kept tightly sealed under an inert atmosphere such as nitrogen to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
