For any chemical raw material used in industrial applications, understanding its purity and specifications is paramount to ensuring consistent performance and product quality. 9,10-Dihydro-9-Oxa-10-Phosphaphenanthrene-10-Oxide (DOPO), a critical halogen-free flame retardant, is no exception. Its effectiveness, particularly in sensitive applications like electronics and advanced polymers, directly correlates with its purity and adherence to established specifications. As a leading manufacturer and supplier of DOPO in China, we emphasize the importance of these parameters for our clients.

DOPO, identified by CAS number 35948-25-5, is typically supplied with a minimum purity of 98%. This high level of purity is essential because impurities can negatively affect its flame retardant capabilities, thermal stability, and compatibility with host polymers. For instance, in epoxy resin formulations for printed circuit boards, even minor variations in DOPO purity can lead to inconsistencies in dielectric properties, thermal resistance, and overall product reliability. Therefore, procurement managers and R&D scientists must prioritize sourcing from manufacturers who guarantee high purity.

Key specifications for DOPO often include its melting point, appearance, and molecular weight. The melting point, generally falling within the range of 115-120°C, is a critical indicator of purity. Any significant deviation from this range can suggest the presence of contaminants or improper synthesis. The appearance, typically a white solid or crystalline powder, also serves as a visual cue for quality. The molecular weight of approximately 216.17 g/mol is a fundamental chemical property that dictates its incorporation into polymer chains and its effectiveness in flame retardant mechanisms.

When you decide to buy DOPO, it is crucial to work with a supplier that provides comprehensive documentation, including Certificates of Analysis (CoA) for each batch. A CoA details the actual test results for purity, melting point, and other relevant parameters, ensuring that the material meets the advertised specifications. As a reputable China-based manufacturer, we ensure that all our DOPO products are accompanied by thorough CoAs, giving our customers the confidence they need in their material sourcing.
