Description

Trinaphthyl Phosphine CAS NO 28653-22-7 is a high-purity, sterically hindered tertiary phosphine ligand, prized for its electron-rich and bulky naphthyl substituents. This compound matters for its exceptional ability to stabilize low-valent metal centers and modulate catalytic activity in complex organic transformations. It is a critical reagent for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise control over metal-catalyzed cross-coupling and polymerization reactions.

Application

• As a specialized ligand in transition metal catalysis, particularly for palladium- and nickel-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Negishi).
• Key component in the synthesis of pharmaceutical intermediates and active pharmaceutical ingredients (APIs) requiring high selectivity.
• Used in the development of advanced polymeric materials, including specialty plastics and electronic materials, via controlled polymerization.
• Employed in agrochemical research for creating novel, high-performance active ingredients.
• Acts as a stabilizing agent for sensitive organometallic complexes and catalysts.
• Facilitates academic and industrial R&D in organometallic chemistry and homogeneous catalysis.

Quality Control

Our Trinaphthyl Phosphine is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for catalytic and synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) due to its sensitivity to oxidation. Keep away from heat and incompatible materials.
