For procurement managers and R&D scientists in the chemical and manufacturing sectors, sourcing raw materials like Diphenyl Ketone (BP) requires a strategic approach. Understanding the product's specifications, applications, and how to engage with suppliers is key to ensuring a smooth and cost-effective procurement process. This guide provides essential information for buyers looking to purchase Diphenyl Ketone (BP), CAS No. 119-61-9.

Understanding Diphenyl Ketone (BP)

Diphenyl Ketone, also known by its synonyms UV500 and Photoinitiator-BP, is an organic compound primarily recognized for its role as a UV absorption agent and a highly effective free-radical photoinitiator. It is characterized by its white to off-white flake or crystal powder appearance and typically exhibits a purity of 99.0% or higher. Its physical properties, such as a melting point between 47-51°C and a boiling point of 305°C, are important considerations for handling and formulation.

Key Applications Driving Demand

The demand for Diphenyl Ketone is driven by its versatility across several industries:

  • UV Curing: It is extensively used in UV-curable coatings, inks, and adhesives, where it initiates rapid polymerization upon UV exposure, leading to quick drying and enhanced physical properties like scratch resistance and gloss.
  • Pharmaceutical Intermediates: BP serves as a building block in the synthesis of various pharmaceutical compounds, making it a valuable material for the pharmaceutical industry.
  • Fragrances and Flavors: It is also utilized in the fragrance and spice industries to impart specific aromatic qualities.

What Buyers Should Look For When Sourcing

When you plan to buy Diphenyl Ketone, it's crucial to focus on several key aspects to ensure you are obtaining a product that meets your quality and performance needs:

  • Purity Levels: Always verify the assay or purity percentage. For most industrial applications, especially in UV curing and pharmaceuticals, a purity of ≥99.0% is standard and recommended.
  • CAS Number Verification: Confirming the CAS number (119-61-9) ensures you are sourcing the correct chemical compound.
  • Physical Appearance: While usually consistent, understanding the expected appearance (flake or crystal powder) can be a quick check.
  • Supplier Reliability: It is vital to partner with reputable manufacturers or suppliers, particularly those based in China, known for competitive pricing and robust supply chains. Look for suppliers who provide detailed technical data sheets and certificates of analysis.
  • Pricing and Quotes: Obtaining quotes from multiple suppliers will help you secure the best price for Diphenyl Ketone. Inquire about bulk purchase discounts and payment terms.

Engaging with Manufacturers in China

China is a significant global hub for chemical manufacturing. For procurement managers, sourcing Diphenyl Ketone directly from a Chinese manufacturer can offer substantial cost benefits and a stable supply. When reaching out, be clear about your required quantity, specifications, and delivery timelines. Proactive communication can streamline the ordering process and ensure timely delivery.
