Description

Di-I-Butylphosphine is a versatile organophosphorus compound widely used as a key ligand and precursor in advanced chemical synthesis. Its primary value lies in its strong electron-donating and steric properties, which are critical for creating highly active and selective catalysts. This chemical is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors, particularly for cross-coupling reactions and the development of novel metal complexes.

Application

• As a ligand in homogeneous catalysis, particularly for palladium- and nickel-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Negishi).
• Precursor for the synthesis of specialized phosphine ligands with tailored steric and electronic properties.
• Intermediate in the production of photoinitiators and other functional additives for polymer chemistry.
• Used in agrochemical research for developing novel active ingredients.
• Employed in material science for creating metal-organic frameworks (MOFs) and semiconductor precursors.
• As a reducing agent in specific organic transformations.

Quality Control

Our Di-I-Butylphosphine is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 standards for traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C. Due to its pyrophoric nature and sensitivity to oxidation, containers must be kept sealed and away from heat, sparks, and open flames.
