Description

Dichloro N,n-Diethylphosphoramidite is a highly reactive organophosphorus compound widely used as a key intermediate in chemical synthesis. Its primary value lies in its role as a versatile building block for constructing complex phosphorus-containing molecules, particularly in the production of ligands, flame retardants, and agrochemicals. This product is essential for research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors seeking to develop new active ingredients or functional materials.

Application

• Phosphite Ligand Precursor: A critical intermediate for synthesizing chiral and achiral phosphite ligands used in asymmetric catalysis and transition metal complexes.
• Agrochemical Synthesis: Employed in the manufacture of organophosphate insecticides, herbicides, and plant growth regulators.
• Flame Retardant Production: Serves as a building block for creating phosphorus-based flame retardant additives for polymers and plastics.
• Pharmaceutical Intermediate: Used in the synthesis of nucleotide analogs and other bioactive molecules containing phosphorus.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D in organophosphorus chemistry and material science.
• Polymer Modification: Acts as a monomer or modifying agent in the synthesis of specialty polymers with tailored properties.

Quality Control

Our Dichloro N,n-Diethylphosphoramidite is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profiling, to ensure high purity and consistency. We provide detailed Certificates of Analysis (COA) with every shipment, documenting key parameters such as identity, purity, and moisture content. Our quality systems are designed to meet the rigorous demands of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Due to its highly volatile, hygroscopic, and easily oxidized nature, the container must be kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents.
