4-Bromopyrazole Chemical Properties,Usage,Production

  • 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.
