| | 1,3-Cyclopentanedione Usage And Synthesis |
| Chemical Properties | white to cream crystalline powder | | Uses | 1,3-Cyclopentanedione was used in the synthesis of chemical probes for selective labeling of sulfenic acid proteins. It was also used to synthesize enaminones with possible anticonvulsant activity. | | Definition | ChEBI: Cyclopentane-1,3-dione is a beta-diketone and a member of cyclopentanones. | | Synthesis Reference(s) | Journal of the American Chemical Society, 102, p. 2095, 1980 DOI: 10.1021/ja00526a059 | | Purification Methods | Purify the dione by Soxhlet extraction with CHCl3. The CHCl3 is evaporated and the residue is recrystallised from EtOAc and/or sublimed at 120o/4mm. [IR: Boothe et al.
