For procurement managers and R&D scientists in the chemical and polymer industries, understanding the nuances of sourcing key intermediates is critical. This guide focuses on 2,3-Dimethyl-2,3-diphenylbutane (CAS 1889-67-4), a compound valued for its roles as a high-energy plastic initiator and a flame retardant synergist. We’ll explore its applications and provide insights on how to best buy this chemical online from reputable sources.

What is 2,3-Dimethyl-2,3-diphenylbutane?

Also known by synonyms like Dicumene or Perkadox 30, 2,3-Dimethyl-2,3-diphenylbutane is an organic compound widely used in industrial applications. Its chemical structure allows it to function effectively as a non-peroxide initiator for radical reactions, as a grafting agent for polymer modification, and critically, as a synergist to enhance the performance of flame retardant systems.

Key Applications Driving Demand

The demand for 2,3-Dimethyl-2,3-diphenylbutane stems from its critical functions:

  • Polymer Initiation: It serves as a high-energy initiator, crucial for the controlled polymerization of monomers such as styrene, acrylates, and methacrylates. This ensures the production of polymers with specific molecular weights and properties.
  • Flame Retardant Synergism: It significantly boosts the efficacy of traditional flame retardants in polymers like polystyrene and polyolefins. This allows for lower loading of primary retardants, reducing costs and minimizing impact on the base polymer's physical attributes. Procurement teams often seek competitive flame retardant synergist price options.
  • Grafting Agent: This compound facilitates the chemical grafting of polymer chains, a vital process for creating co-polymers and modifying existing polymers to achieve enhanced performance characteristics, such as improved impact resistance or surface properties.

Sourcing and Purchasing Considerations

When looking to purchase 2,3-Dimethyl-2,3-diphenylbutane, several factors are important for B2B buyers:

  • Purity and Assay: The compound is typically available with an assay of 97% minimum purity. Higher purity often translates to more consistent and predictable results in sensitive applications.
  • Capacity and Supply Chain: Manufacturers in China offer substantial production capacities, often in the range of 40-60 tons per month. Securing a reliable supplier in China guarantees a stable supply chain, which is critical for uninterrupted production.
  • Packaging: Common packaging includes 1kg/bag or 25kg/drum, suitable for both laboratory and industrial scale requirements.
  • Pricing: Exploring different manufacturer price options is essential. Bulk purchases can significantly reduce the per-unit cost. Comparing quotes from various suppliers will help you secure the best value.

Finding a Reliable Manufacturer

For businesses seeking to buy CAS 1889-67-4, looking for manufacturers with established track records in producing high-purity chemical intermediates is key. Companies specializing in polymer additives and fine chemicals, particularly those located in industrial hubs like China, are well-positioned to meet these needs. When evaluating a potential supplier, consider their:

  • Quality control processes and certifications.
  • Production capacity and lead times.
  • Technical support and customer service.
  • Competitive pricing structures for bulk orders.

By focusing on these aspects, procurement managers can confidently source 2,3-Dimethyl-2,3-diphenylbutane, ensuring their product development and manufacturing processes are supported by high-quality chemical intermediates.
