For procurement managers and formulation scientists in the chemical industry, a thorough understanding of product specifications is fundamental to making informed purchasing decisions. 3,3,4,4-Biphenyltetracarboxylic Dianhydride (BPDA), identified by its CAS number 2420-87-3, is a high-value chemical intermediate that demands precise technical details. As a professional manufacturer and supplier of BPDA in China, we are committed to providing comprehensive information to our clients.

The primary specification for BPDA is its purity, which typically reaches a minimum of 99.5%. This high level of purity is crucial for its intended applications, particularly in the synthesis of high-performance polymers like polyimides, where even trace impurities can affect the final product’s thermal stability, mechanical strength, and electrical insulation properties. The physical appearance of BPDA is a white powder, a standard characteristic that aids in its visual quality assessment during handling and processing.

Understanding the molecular properties is also key. BPDA has a molecular formula of C16H6O6 and a molecular weight of approximately 294.22 g/mol. Its melting point, typically in the range of 299-305°C, is a critical parameter indicating its thermal stability and suitability for high-temperature polymerization processes. These specifications are vital for formulators aiming to achieve precise reaction kinetics and desired polymer chain structures.
