For procurement managers in the chemical, pharmaceutical, and material science sectors, sourcing raw materials with consistent quality and reliable supply is a cornerstone of successful operations. Phenothiazine (CAS 92-84-2), a compound with a light yellow appearance, is one such critical raw material, valued for its diverse applications ranging from polymerization inhibition to serving as a vital intermediate in complex syntheses. This guide focuses on what procurement professionals need to know when looking to buy Phenothiazine.

Understanding Phenothiazine's Value Proposition:

Phenothiazine's versatility stems from its unique chemical structure and properties. It is primarily recognized for:

  • Polymerization Inhibition: Essential for stabilizing reactive monomers like acrylic acid, acrylates, and vinyl acetate, preventing uncontrolled polymerization during storage and processing.
  • Antioxidant Properties: Enhances the longevity of synthetic rubber and lubricating oils by preventing oxidative degradation.
  • Synthetic Intermediate: A crucial building block in the synthesis of pharmaceuticals, dyes, and agrochemicals.

Key Considerations for Procurement:

When sourcing Phenothiazine, several factors are paramount for procurement managers:

  1. Purity: For most applications, especially in pharmaceutical and fine chemical synthesis, high purity (typically ≥99%) is non-negotiable. Impurities can negatively affect reaction yields, product quality, and regulatory compliance.
  2. Consistency of Supply: Relying on a manufacturer with a robust production capacity and a stable supply chain is vital to avoid disruptions in your production schedule.
  3. Technical Specifications: Ensure the supplier provides detailed technical data sheets, including CAS number (92-84-2), molecular formula (C12H9NS), melting point, and assay results.
  4. Regulatory Compliance: Verify that the product and supplier meet relevant regulatory standards, such as REACH if importing into Europe.
  5. Pricing and Value: While cost is a factor, it should be balanced against quality and reliability. Understanding the market price for high-purity Phenothiazine from reputable Chinese manufacturers is essential for making informed purchasing decisions.
