3,3',4,4'-Benzophenonetetracarboxylic Dianhydride, or BTDA (CAS 2421-28-5), is a chemical compound of significant interest in material science and polymer chemistry. As a distinguished manufacturer and supplier, we aim to provide comprehensive information on this vital intermediate, assisting researchers and procurement professionals in understanding its value and potential applications. This article delves into BTDA's key properties, explores its diverse applications, and guides you on how to best inquire about its purchase.

The chemical structure of BTDA, featuring a benzophenone core flanked by two dianhydride groups, dictates its reactivity and the properties of the polymers it helps create. Typically supplied as a white to pale yellow powder, BTDA exhibits a high melting point, generally between 219-226°C. Its purity is a critical factor, with industrial grades often specified at ≥ 99.5% assay. This high purity is essential for the synthesis of high-performance polymers that require precise control over molecular architecture and minimal impurities.

The primary utility of BTDA lies in its role as a monomer for the synthesis of polyimides. These polymers are lauded for their exceptional thermal stability, capable of withstanding high operational temperatures without significant degradation. This makes BTDA-based polyimides ideal for applications in demanding environments, such as components in aerospace, high-temperature insulation, and specialized electronic parts. The resulting materials often possess superior mechanical strength, contributing to the longevity and reliability of products.

Furthermore, BTDA is a key component in the development of materials for advanced electronic applications. Its use in creating dielectric layers for OFET memory devices, for example, highlights its contribution to the miniaturization and enhanced functionality of electronic components. The intrinsic properties of BTDA-derived polyimides also lend themselves to use in other specialized areas, including photocatalytic degradation of pollutants and the development of high-performance films and coatings.
