Description

Ethyl Dichlorophosphate is a versatile organophosphorus compound widely used as a key intermediate in chemical synthesis. Its high reactivity makes it an essential building block for creating more complex molecules, particularly in the pharmaceutical and agrochemical sectors. This product is critical for manufacturers requiring a reliable and high-purity reagent for phosphorylation reactions, flame retardant production, and specialty polymer synthesis.

Application

• Pharmaceutical Intermediate: A crucial reagent in the synthesis of active pharmaceutical ingredients (APIs), particularly for prodrugs and nucleotide analogs.
• Agrochemical Synthesis: Used in the production of organophosphate insecticides, herbicides, and plant growth regulators.
• Flame Retardant Precursor: Serves as a key intermediate in manufacturing phosphorus-based flame retardants for plastics and textiles.
• Polymer Modification: Employed as a modifying agent to introduce phosphate groups into polymers, enhancing properties like adhesion or flame resistance.
• Chemical Research & Development: A valuable building block in organic synthesis laboratories for creating novel organophosphorus compounds.
• Ligand and Catalyst Preparation: Used in the preparation of specialized ligands and catalysts for metal-organic chemistry.

Quality Control

Our Ethyl Dichlorophosphate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support our global B2B clients with full traceability and documentation to meet ISO and cGMP standards where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
