Heterocyclic building block
Serves as an imidazolidinone (cyclic urea) building block for the construction of more elaborate heterocyclic and nitrogen-containing molecules in chemical synthesis.
Pharmaceutical intermediate
Used in medicinal chemistry as an intermediate scaffold during early-stage discovery and route-development work, where the cyclic urea motif is a common pharmacophore.
Aniline functionalisation
The free aromatic amine provides a reactive handle for acylation, sulfonylation, reductive amination, diazotisation and amide-bond formation, enabling rapid analogue generation.
Library and analogue synthesis
The bifunctional structure supports parallel and library synthesis, allowing researchers to diversify around both the aniline nitrogen and the imidazolidinone ring.
Laboratory research reagent
Supplied as a reagent for laboratory-scale research and method development by chemists working in academic, contract-research and industrial settings.
