Ethyl 1-piperazinecarboxylate(CAT: R032264) is a versatile chemical intermediate featuring a piperazine ring substituted with an ethyl carbamate group at the nitrogen (N1) position. This structure combines the reactivity of a secondary amine with the stability of a carbamate ester, making it useful in the synthesis of pharmaceuticals, bioactive heterocycles, and CNS-targeting agents. It is often employed as a building block in medicinal chemistry for drug development and structure–activity relationship studies. Ethyl 1-piperazinecarboxylate is typically supplied as a clear to pale yellow liquid, soluble in polar solvents, and must be handled under standard laboratory conditions.
