For professionals in the chemical and materials sectors, a thorough understanding of key intermediates is essential for successful product development and manufacturing. 4-Chloroformylphthalic Anhydride, identified by CAS number 1204-28-0, is one such compound that warrants attention due to its critical role in specific high-value applications, most notably in the production of dental composite resin materials. As a trusted manufacturer and supplier, we aim to provide clarity on this important chemical intermediate.

Key Properties and Specifications

4-Chloroformylphthalic Anhydride is characterized by its physical appearance as a white crystalline powder. Its chemical formula is C9H3ClO4, with a molecular weight of 210.57. A significant specification that buyers should always look for is its purity, often indicated by the isoquinoline content, which for high-grade material typically exceeds 98.0%. This purity level is critical for its effective use in downstream applications, ensuring predictable chemical reactions and reliable performance of the final product. Packaging is typically provided in drums, such as 25 kg/drum, suitable for industrial handling.

Primary Application: Dental Composite Resins

The most prominent application for 4-Chloroformylphthalic Anhydride is its use as a key ingredient in dental composite resin materials. These materials are essential in modern dentistry for tooth restoration, fillings, and cosmetic bonding. The intermediate's reactive nature allows it to participate effectively in the polymerization process, contributing to the strength, durability, and aesthetic qualities of the cured dental composite. For manufacturers in the dental materials industry, securing a consistent supply of high-purity 4-Chloroformylphthalic Anhydride is vital for maintaining product quality and performance standards.

Storage and Handling Recommendations

Proper storage and handling are crucial for maintaining the integrity of 4-Chloroformylphthalic Anhydride. It should be stored in completely packed, lightly sealed containers to protect it from moisture and contamination. Ideally, storage areas should be well-ventilated, kept away from open flames and high temperatures, and the material should be stored separately from incompatible substances like oxidants and strong acids. Adhering to these guidelines ensures the chemical's stability and safety.
