Description

Dibromo(Phenyl)Phosphine is a versatile organophosphorus compound that serves as a key synthetic intermediate in advanced chemical manufacturing. Its primary value lies in its reactivity as a brominated phosphine, enabling the construction of complex phosphorus-containing ligands and materials. This product is essential for R&D and production teams in the pharmaceutical, agrochemical, and specialty chemical sectors seeking to develop novel catalysts or active ingredients.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel drug candidates, particularly those targeting kinase inhibition.
• Catalyst Ligand Precursor: A key building block for creating specialized phosphine ligands used in cross-coupling reactions (e.g., Suzuki, Heck).
• Agrochemical Synthesis: Employed in the production of advanced herbicides, fungicides, and plant growth regulators.
• Flame Retardant Additive: Acts as a reactive intermediate in the manufacture of brominated phosphorus-based flame retardants for polymers.
• Material Science Research: Utilized in the development of novel phosphorous-containing polymers and electronic materials.
• Organic Synthesis Reagent: Serves as a phosphorylating or brominating agent in complex multi-step organic transformations.

Quality Control

Our Dibromo(Phenyl)Phosphine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets the high-purity standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and safety parameters is provided with every shipment to guarantee traceability and compliance.

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 sensitivity to moisture and air, the container should be kept sealed and handled in a glovebox or under a continuous inert gas purge when opened. Recommended long-term storage temperature is 2-8°C.
