For professionals in the chemical and material science industries, sourcing high-quality intermediates is paramount to product success. One such critical compound is 4-Chloroformylphthalic Anhydride, identified by its CAS number 1204-28-0. This article aims to guide B2B procurement managers and R&D scientists on where and why to buy this essential organic intermediate, focusing on quality, applications, and reliable sourcing channels from China.

Understanding 4-Chloroformylphthalic Anhydride (CAS 1204-28-0)

4-Chloroformylphthalic Anhydride is recognized for its role as a key building block in various synthesis processes. Typically appearing as a white crystalline powder, its precise chemical structure and high purity are critical for its intended applications. The most prominent use is within the dental industry, where it serves as a vital component in the formulation of advanced dental composite resin materials. These composites require intermediates that offer consistent performance, stability, and reactivity, all of which are hallmarks of high-purity 4-Chloroformylphthalic Anhydride.

Key Applications and Why Purity Matters

The primary application for 4-Chloroformylphthalic Anhydride is in dental composites. In this context, the intermediate contributes to the mechanical strength, curing properties, and longevity of dental fillings and restorative materials. For product formulators, ensuring the purity of the starting materials directly impacts the final product's efficacy and safety. Therefore, when you are looking to buy, prioritizing suppliers who guarantee a purity level of ≥98.0% for 4-Chloroformylphthalic Anhydride is essential. Beyond dental applications, this compound can also be a valuable asset in other specialty organic synthesis projects requiring a reactive anhydride and acyl chloride functional group.

Navigating the Supply Chain: Finding a Reliable Manufacturer in China

China has emerged as a global hub for chemical manufacturing, offering a wide array of organic intermediates. For businesses seeking to purchase 4-Chloroformylphthalic Anhydride, identifying a reputable manufacturer or supplier in China can provide significant advantages, including competitive pricing and accessibility. When evaluating potential partners, look for suppliers who:

  • Clearly state product specifications, including purity levels and CAS numbers.
  • Provide detailed product documentation, such as Certificates of Analysis (CoA).
  • Have established quality control processes.
  • Offer flexible packaging and shipping options to meet diverse logistical needs.
  • Demonstrate a commitment to customer service and timely communication, crucial for managing international procurement.

Partnering with an experienced chemical manufacturer in China ensures that you not only secure a cost-effective supply but also maintain the quality standards necessary for your advanced material formulations. Remember to always request samples for evaluation before committing to large orders to verify suitability for your specific manufacturing processes.
