| | 4-Bromopyrazole Usage And Synthesis |
| Chemical Properties | White to cream crystalline powder | | Uses | As a mono substituted pyrozole, 4-Bromopyrazole can be used as Inhibitor of human liver alcohol dehydrogenase and used in mutagenicity study with the L-arabinose resistance test of Salmonella typhimurium. | | Uses | 4-Bromopyrazole can be used as starting material employed in a synthesis of 1,4′-bipyrazoles and in suzuki reaction. | | General Description | 4-Bromopyrazole is a pyrazole derivative. It is reported to react with titanium tetrachloride to afford binary adducts. Mutagenicity of 4-bromopyrazole has been tested using the L-arabinose forward mutation assay of Salmonella typhimurium. It is reported to inhibit the oxidative phosphorylation, the ATP-32P exchange reaction, and energy dependent and independent calcium uptake. | | References |
