1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Computed Properties of C4H4BrNO2

And the article was included in ACS Applied Energy Materials in 2022.Computed Properties of C4H4BrNO2 This article mentions the following:

Linear crosslinked and star crosslinked anion exchange membranes (AEMs) are reported in this work, namely, lcQPPO (linear crosslinked quaternized poly(2,4-dimethyl-1,4-phenylene oxide) (PPO)) and scDQPPO (star crosslinked quaternized PPO). Compared with original quaternized PPO (QPPO), crosslinked AEMs show a restrained swelling degree. But, due to the hindrance of a crosslinking polymer matrix, lcQPPO membranes show decreased ionic conductivity For scDQPPO, its wide and connective ion channels are beneficial to the conduction of OH–, exhibiting increased ionic conductivity Besides, the aggregated and crosslinked polymer networks in scDQPPO enhance the chem. stability and mech. properties of the AEMs. Specifically, for scDQPPO-40, a high OH– conductivity of 100.7 mS cm-1 and a low swelling degree of 20.7% are achieved at 80°C. The tensile strength and elongation at break of wet scDQPPO-40 at 25°C are 16.7 MPa and 18.0%. After immersing in 1 M NaOH at 80°C for 30 days, the loss of ionic conductivity and weight for scDQPPO-40 is 24.2 and 14.8%, with the degradation of tensile strength and elongation at break of 22.2% and 26.7%, resp. On the basis of the membrane, a fuel cell performance of 0.577 W cm-2 is demonstrated at 60°C, while, for QPPO-40 and lcQPPO-60, their fuel cell peak power densities are only 0.250 and 0.215 W cm-2. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Computed Properties of C4H4BrNO2).
