For procurement managers and R&D scientists in the chemical and pharmaceutical industries, sourcing high-quality raw materials is paramount. Diphenylphosphine Oxide (DPPO), with CAS number 4559-70-0, stands out as a critical organophosphorus compound. This article serves as a comprehensive guide for buyers looking to purchase DPPO, focusing on its applications, quality considerations, and the benefits of sourcing from reputable China manufacturers.

Understanding Diphenylphosphine Oxide (DPPO)

Diphenylphosphine Oxide (DPPO) is characterized by its chemical formula (C6H5)2P(O)H and its typical appearance as a white crystal. Its melting point is around 56-57 °C, and it is soluble in various polar organic solvents. The compound is highly valued for its versatility in chemical synthesis. It acts as a key intermediate in the production of a wide array of organophosphorus compounds, including those used in advanced pharmaceuticals, effective agrochemicals, and specialized industrial materials.

Key Applications Driving Demand

The demand for DPPO is fueled by its multifaceted applications:

  • Pharmaceutical Intermediates: DPPO is extensively used in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs). Its role in developing new therapeutic agents makes it indispensable for pharmaceutical research and development. Buyers seeking to procure pharmaceutical intermediates will find DPPO a valuable addition to their supply chain.
  • Organophosphorus Synthesis: As a precursor to various organophosphorus compounds, DPPO is crucial for reactions such as cross-coupling with aryl halides, leading to diphenylarylphosphines. These are often used as chiral ligands in asymmetric catalysis, enhancing the efficiency and selectivity of chemical transformations.
  • Agrochemicals: The compound is utilized in the creation of pesticides and herbicides, contributing to advancements in crop protection and agricultural productivity.
  • Materials Science: DPPO can be integrated into polymers to impart desirable properties, such as enhanced flame retardancy, making it useful for manufacturing safer materials for construction and textiles.

What to Look for When Buying DPPO

When purchasing Diphenylphosphine Oxide, several factors are critical to ensure you receive a product that meets your specifications:

  • Purity: Look for manufacturers that guarantee high purity levels, typically 97% or higher, as specified in the product's technical data. This ensures reliable and reproducible synthesis outcomes.
  • CAS Number Verification: Always confirm the CAS number is 4559-70-0 to ensure you are obtaining the correct compound.
  • Supplier Reliability: Partner with established manufacturers and suppliers who can demonstrate consistent product quality, reliable delivery, and adherence to international standards.
  • Packaging and Handling: Ensure the product is appropriately packaged for safe transport and storage, typically under inert atmosphere conditions.

Sourcing from China: Advantages for Buyers
