Description

Dichlorophenylphosphine is a versatile organophosphorus compound widely used as a key synthetic intermediate. Its primary value lies in its role as a crucial building block for the preparation of phosphine ligands, flame retardants, and other specialty chemicals. This product is essential for research and development laboratories, as well as industrial-scale production facilities in the pharmaceutical, agrochemical, and material science sectors. We supply high-purity Dichlorophenylphosphine CAS NO 644-97-3 to meet the stringent demands of advanced chemical synthesis.

Application

• Phosphine Ligand Synthesis: A fundamental precursor for creating a wide array of chiral and achiral phosphine ligands used in homogeneous catalysis, particularly in cross-coupling reactions.
• Pharmaceutical Intermediates: Serves as a critical building block in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Agrochemical Production: Used in the manufacture of pesticides, herbicides, and plant growth regulators where phosphorus-containing structures are required.
• Flame Retardant Formulation: Acts as an intermediate in the production of organophosphorus flame retardants for polymers and textiles.
• Material Science: Employed in the synthesis of novel polymers, resins, and coatings with specific thermal or chemical resistance properties.
• Chemical Research: A valuable reagent in academic and industrial R&D for exploring new organophosphorus chemistry and developing novel synthetic methodologies.

Quality Control

Our Dichlorophenylphosphine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment. We are committed to meeting the quality standards required for research and industrial applications.

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 and moisture-sensitive nature, containers should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
