Cas no 294877-41-1 (1-(4-Bromophenyl)-1H-pyrazole-4-carbaldehyde)
1-(4-Bromophenyl)-1H-pyrazole-4-carbaldehyde is a brominated pyrazole derivative featuring a reactive aldehyde functional group, making it a versatile intermediate in organic synthesis. Its structure combines a 4-bromophenyl substituent with a pyrazole core, offering distinct reactivity for cross-coupling reactions, such as Suzuki or Buchwald-Hartwig couplings, due to the bromine moiety. The aldehyde group enables further derivatization through condensation or nucleophilic addition reactions, facilitating the synthesis of heterocyclic compounds, pharmaceuticals, or functional materials. This compound is particularly valuable in medicinal chemistry for constructing bioactive scaffolds. High purity and well-defined reactivity ensure consistent performance in research and industrial applications.
