'''吡唑烷'''是有两个相邻[[氮]]原子的五元[[杂环化合物]]，化学式[[C3H8N2|C<sub>3</sub>H<sub>8</sub>N<sub>2</sub>]]。

== 制备==
吡唑烷可以由[[1,3-二氯丙烷]]或[[1,3-二溴丙烷]]和[[肼]][[环化]]而成：<ref name=buhle />

:<math>\mathrm{Cl{-}(CH_2)_3{-}Cl\ +\ N_2H_4\ \xrightarrow {\Delta T}\ C_3H_8N_2\ +\ 2 HCl}</math>
:<math>\mathrm{Br{-}(CH_2)_3{-}Br\ +\ N_2H_4\ \xrightarrow {\Delta T}\ C_3H_8N_2\ +\ 2 HBr}</math>

== 性质==
吡唑烷是液体，熔点 10–12&nbsp;°C，沸点 138&nbsp;°C。它在空气中稳定，但容易[[潮解]]。<ref name=buhle />
