Definition of piperazine in English:

piperazine

noun pʌɪˈpɛrəziːnpɪˈpɛrəziːn

mass nounChemistry

A synthetic crystalline compound with basic properties, sometimes used as an anthelmintic and insecticide.
〔化〕哌嗪，对二氮己环，胡椒嗪
A heterocyclic compound; chemical formula: C₄H₁₀N₂
Example sentencesExamples
- The final step involved a nucleophilic substitution of the 2-chloro group by piperazine at high temperatures.
- Fluphenazine is a piperazine phenothiazine that is structurally similar to perphenazine and prochlorperazine.
- The interaction energy between the piperazine and the DNA does not alter significantly during the structural changes, suggesting entropy as the driving force for the transitions.
- Thus, the piperazine ring rotates while the rest of the molecule stays in the starting x-ray conformation during the simulation.
- The piperazine end of the molecule extends partially into the GC region of the DNA.

Origin

Late 19th century: from piperidine + azine.
