Description

Chloro-Diphenyl-Phosphane is a versatile organophosphorus compound widely used as a key building block in organic synthesis. Its primary value lies in its role as a precursor for phosphine ligands and other phosphorus-containing fine chemicals, which are critical in catalysis and materials science. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop new catalysts, flame retardants, or active pharmaceutical ingredients.

Application

• Phosphine Ligand Synthesis: A fundamental precursor for the preparation of chiral and achiral phosphine ligands used in homogeneous catalysis, including cross-coupling reactions.
• Pharmaceutical Intermediates: Serves as a key building block in the synthesis of organophosphorus compounds with potential biological activity.
• Agrochemical Manufacturing: Used in the production of phosphorus-based pesticides, herbicides, and plant growth regulators.
• Flame Retardant Development: Acts as an intermediate in the synthesis of organophosphate flame retardants for polymers and textiles.
• Material Science Research: Employed in the creation of novel phosphorus-containing polymers, coatings, and electronic materials.
• Catalyst Preparation: Utilized to synthesize metal-phosphine complexes for hydrogenation, hydroformylation, and other industrial catalytic processes.

Quality Control

Our Chloro-Diphenyl-Phosphane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling, to meet the stringent requirements of our global B2B clients. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

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 place. Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed after each use to minimize exposure to moisture and air. Recommended long-term storage temperature is 2-8°C.
