Cyclobutane-1,2,3,4-tetracarboxylic Dianhydride, commonly known as CBDA and bearing the CAS number 4415-87-6, is a fascinating chemical compound with a significant role in both materials science and organic synthesis. As a leading manufacturer and supplier, we aim to provide clarity on its essential characteristics and widespread applications, helping procurement managers and research scientists make informed decisions when sourcing this intermediate.
The physical properties of CBDA are key to its utility. It typically presents as a white powder, with a melting point exceeding 300°C, indicating high thermal stability. This characteristic is crucial for its application in high-temperature polymer processing. Chemically, CBDA is an organic anhydride, characterized by its C8H4O6 molecular formula and a molecular weight of 196.11 g/mol. Its purity, often exceeding 98.0%, is a critical factor for its effectiveness in demanding applications.
The primary applications of CBDA are diverse. In the realm of materials science, it serves as a vital monomer in the preparation of polyimide (PI) films. These polyimides exhibit excellent electrical characteristics and optical transparency, making them ideal for advanced applications such as high-performance organic thin-film transistors (OTFTs) and photonic devices. The ability of CBDA-derived polyimides to withstand high temperatures further enhances their suitability for cutting-edge electronic components. Researchers and developers looking to buy these advanced materials often seek the precise chemical building blocks like CBDA.
In organic synthesis, CBDA is recognized as a valuable reactant for preparing biologically and pharmacologically active molecules. Its reactive anhydride groups allow for efficient derivatization, opening pathways to complex molecular structures relevant to the pharmaceutical industry. For any scientist or procurement specialist aiming to purchase CBDA for these synthesis routes, partnering with a reputable manufacturer from China ensures access to quality materials at competitive prices. We pride ourselves on being such a supplier, committed to delivering excellence in every batch.
