1-(3,4-Dichlorobenzyl)piperazine
1-(3,4-Dichlorobenzyl)piperazine (CAS 55513-17-2) is an N-substituted piperazine building block with the molecular formula C11H14Cl2N2 and a molecular weight of 245.15 g/mol. It is supplied as a liquid of approximately 97% assay (refractive index n20/D 1.5710, density 1.225 g/mL at 25 degC). The free secondary amine on the piperazine ring makes it a versatile intermediate for organic synthesis, medicinal-chemistry research and the preparation of more complex heterocyclic compounds.

Heterocyclic building block
Used as a halogenated piperazine intermediate in chemical synthesis. The reactive secondary N-H allows acylation, alkylation, sulfonylation and reductive amination to construct larger molecular scaffolds.
Pharmaceutical and medicinal-chemistry research
The N-benzylpiperazine motif is a common feature in drug-discovery programmes. This compound serves as a research-grade intermediate for the exploration of new piperazine-based structures.
Library and scaffold synthesis
The dichlorobenzyl group provides a defined aromatic handle for analogue series, supporting structure-activity studies and the assembly of compound libraries in laboratory settings.
Fine-chemical and custom synthesis
Suitable as a starting material or intermediate in multi-step routes where a substituted piperazine fragment is required. Quantities can be supplied to support process development and scale-up evaluation.
