1-(2-Fluorophenyl)piperazine
1-(2-Fluorophenyl)piperazine (CAS 1011-15-0) is a fluorinated heterocyclic building block with the molecular formula C10H13FN2 and a molar mass of 180.22 g/mol. It combines an ortho-fluorinated phenyl ring with a piperazine scaffold, giving a reactive secondary amine widely used in chemical synthesis. Tech Serve Solutions supplies it as a research-grade reagent (assay 97%), principally as an intermediate in the preparation of neurologically active compounds and other fine-chemical structures.

Pharmaceutical intermediate
Serves as an intermediate in the synthesis of neurologically active compounds. The free secondary nitrogen of the piperazine ring provides a convenient handle for alkylation, acylation and related coupling steps in medicinal-chemistry routes.
Fluorinated building block
The ortho-fluorine on the aromatic ring is a valued structural motif in modern drug discovery, used to fine-tune the electronic profile, metabolic behaviour and binding of candidate molecules built around an arylpiperazine core.
Heterocyclic scaffold for synthesis
As a substituted piperazine, it is employed in the construction of more elaborate heterocyclic systems and is a common scaffold in exploratory and discovery chemistry programmes.
Research and laboratory reagent
Supplied at 97% assay for use in research, method development and small-scale synthesis where a defined, consistent ortho-fluoro arylpiperazine reagent is required.
