1,2,4,5-Benzenetetracarboxylic Dianhydride-d2

1,2,4,5-Benzenetetracarboxylic Dianhydride-d2, also known as BTDA-d2, is a deuterated derivative of the organic compound BTDA. It is a white crystalline powder that is primarily used in the field of polymer chemistry. Its chemical formula is C10D2O6, and it has a molecular weight of 226.2 g/mol. BTDA-d2 is commonly used as a labeling agent in NMR experiments, where it is used to detect the presence of specific functional groups in a sample. It is also used as a building block in the synthesis of various polymers and copolymers. Its deuterated nature makes it ideal for these applications, as it provides a unique NMR signature that can be easily distinguished from other compounds in a sample. In terms of chemical properties, BTDA-d2 is a dianhydride, which means that it contains two anhydride functional groups (-C(=O)-O-C(=O)-) that are highly reactive. It is soluble in polar solvents such as dimethyl sulfoxide (DMSO) and N,N-dimethylformamide (DMF), but is insoluble in non-polar solvents such as hexane and chloroform. Overall, BTDA-d2 is a valuable tool in the field of polymer chemistry and NMR spectroscopy, and its unique chemical properties make it an ideal choice for a variety of applications.
