In the competitive landscape of dental materials manufacturing, the quality and performance of composite resins are driven by the integrity of their constituent chemical components. For product development scientists and purchasing managers, understanding the function and sourcing of key intermediates like 4-Chloroformylphthalic Anhydride (CAS 1204-28-0) is vital. This article delves into the importance of this specific organic intermediate for dental applications and offers insights into how to buy it from reliable chemical suppliers.

4-Chloroformylphthalic Anhydride: A Cornerstone for Dental Composites

4-Chloroformylphthalic Anhydride, identified by its CAS number 1204-28-0, is a specialized chemical intermediate that plays a crucial role in the synthesis and performance of modern dental composite resins. As a white crystalline powder, its consistent physical form and chemical purity are paramount. These materials are engineered to mimic natural tooth structure, requiring precise formulation. The inclusion of high-purity 4-Chloroformylphthalic Anhydride contributes significantly to the resin's ability to polymerize effectively, achieve desirable mechanical properties such as strength and hardness, and ensure long-term durability in the oral environment.

Why Source from a Trusted Manufacturer?

For dental material manufacturers, the decision to buy 4-Chloroformylphthalic Anhydride is not just about acquisition; it's about quality assurance. A reputable manufacturer will guarantee a high level of purity, typically above 98.0%, and provide batch-consistent material. This is critical because even minor impurities can affect the polymerization kinetics, the final mechanical properties, or the biocompatibility of the dental composite. Working with a dependable supplier, particularly one based in China known for its chemical manufacturing capabilities, can offer advantages in terms of cost-effectiveness and access to bulk quantities. It's advisable to establish a relationship with a manufacturer that can provide consistent supply and reliable technical support.

Procurement Considerations for CAS 1204-28-0

When procurement managers are tasked with sourcing CAS 1204-28-0, several factors come into play. Beyond price, they should consider the supplier's ability to provide comprehensive documentation, including Certificates of Analysis (CoA) detailing purity and physical properties. Understanding the packaging (e.g., 25 kg drums) and recommended storage conditions ensures the material maintains its integrity until it's used in production. Investigating the supplier's experience in exporting chemicals, particularly to your region, is also crucial for a smooth transaction. For those looking to buy this intermediate, engaging with manufacturers who actively participate in global trade and understand regulatory requirements will streamline the process and ensure a secure supply chain for essential dental materials.
