Heterocyclic building block
Used as a piperazine-based scaffold in chemical synthesis. The free secondary amine on the piperazine ring allows alkylation, acylation and sulfonylation to assemble more elaborate molecules.
Aryl iodide for cross-coupling
The para-iodo aryl group is a reactive handle for transition-metal-catalysed cross-coupling reactions such as Suzuki, Sonogashira, Buchwald-Hartwig and related carbon-carbon and carbon-heteroatom bond formations.
Medicinal-chemistry intermediate
Aryl-piperazine motifs are common pharmacophores in drug-discovery programmes. This compound is used as an intermediate and exploratory building block in pharmaceutical and medicinal-chemistry research.
Laboratory research reagent
Functions as a reference building block in method development and structure-activity studies. The salt form aids handling, weighing and storage relative to the free base.
