1-(2,3-Dichlorophenyl)piperazine Hydrochloride: Pharmaceutical Intermediate

Chemical Profile and Uses

1-(2,3-Dichlorophenyl)piperazine hydrochloride is a halogenated piperazine derivative used as a key intermediate in the synthesis of various CNS-active and cardiovascular APIs. The presence of two chlorine atoms on the aromatic ring and a basic piperazine moiety allows for further functionalisation into more complex molecules.

Applications in Drug Development

This intermediate is commonly employed in multi-step synthetic routes where the piperazine ring becomes part of the final active pharmaceutical ingredient. Maintaining consistent quality and impurity control in this step is essential, as impurities can carry through into downstream intermediates.

Quality, Safety and Handling

Quality testing typically covers assay, identification, related substances, residual solvents, and, where relevant, particle size. Operators should handle the material in well-ventilated areas, using gloves, goggles, and protective clothing. Storage in sealed containers away from excessive heat and humidity helps preserve stability.
