For procurement professionals and R&D scientists in specialized chemical sectors, understanding the market and sourcing of critical intermediates is a continuous challenge. This guide is designed to assist you in purchasing 4-Chloroformylphthalic Anhydride (CAS 1204-28-0), a key organic intermediate, with a focus on quality, application relevance, and how to find dependable manufacturers and suppliers, particularly within China.

Understanding 4-Chloroformylphthalic Anhydride: Properties and Applications

4-Chloroformylphthalic Anhydride, identified by its CAS number 1204-28-0, is primarily recognized for its use in the formulation of dental composite resin materials. Its typical appearance is a white crystalline powder, and it is valued for its high purity, often specified at ≥98.0%. This high level of purity is essential for its function, ensuring consistent performance and safety in sensitive applications. For manufacturers of dental materials, sourcing this compound means ensuring the reliability and efficacy of their final products. Beyond its primary use, it can also serve as a valuable intermediate in other fine chemical synthesis processes requiring its specific chemical structure.

Key Considerations When You Buy CAS 1204-28-0

When deciding to purchase 4-Chloroformylphthalic Anhydride, several factors should guide your decision-making process. As a buyer, you must prioritize product quality and supplier reliability. Look for manufacturers who can provide:

  • Certificates of Analysis (CoA): These documents confirm the product's purity (≥98.0%) and other critical specifications.
  • Consistent Batch Quality: Assurance that each batch will meet the same high standards, crucial for reproducible manufacturing processes.
  • Appropriate Packaging: Information on packaging, such as 25 kg drums, and adherence to safe handling and storage guidelines.
  • Responsive Customer Service: A supplier who can quickly answer questions regarding lead times, pricing, and technical aspects.

These elements are crucial for establishing a robust and efficient supply chain for your chemical needs.

Finding the Right Manufacturer and Supplier in China

China is a major global supplier of fine chemicals and intermediates. When looking to buy 4-Chloroformylphthalic Anhydride, working with a Chinese manufacturer can offer competitive pricing and broad accessibility. However, it is vital to vet potential suppliers thoroughly. Seek out manufacturers who specialize in organic intermediates, have established quality control systems, and a proven track record in international trade. Companies that offer samples for evaluation are particularly valuable, allowing you to verify the material's suitability for your specific production requirements. Engaging with suppliers who understand your needs, from technical specifications to delivery timelines, will ensure a successful procurement experience for CAS 1204-28-0.
