01 /Applications

Heterocyclic building block

Serves as a piperazine-based scaffold in chemical synthesis, where the secondary nitrogen of the piperazine ring is readily functionalised through alkylation, acylation or sulfonylation to build more elaborate molecules.

Cross-coupling substrate

The para-bromophenyl group provides a reactive site for palladium-catalysed cross-coupling reactions such as Suzuki, Buchwald-Hartwig and related transformations, allowing introduction of aryl, amino and other substituents.

Pharmaceutical and medicinal chemistry intermediate

Arylpiperazines are a common structural motif in medicinal chemistry. This compound is used in discovery and process research as a starting material for the preparation of candidate molecules and analogues.

Laboratory research reagent

Used as a defined reference and reagent in synthetic and analytical laboratories where a characterised arylpiperazine of known assay and melting range is required.
