'''硫氢化钠'''，化学式為{{化學式|鈉|氫|硫|link=}}，水溶液呈鹼性。

==制备==
===实验室制法===
实验室中可通过无水[[乙醇钠]]与[[硫化氢]]反应制得硫氢化钠：<ref>G. Brauer (Hrsg.): ''Handbook of Preparative Inorganic Chemistry''. 2nd ed., vol. 1, Academic Press 1963, S. 357–8.</ref>
:<math>\rm \ C_2H_5ONa+H_2S\rightarrow NaHS+C_2H_5OH</math>

或将硫化氢通入[[硫化钠]]溶液反应制得硫氢化钠：
:<math>\rm \ H_2S+Na_2S\rightarrow 2NaHS</math>

==用途==
硫氢化钠可用作多组分反应[[Asinger反应]]中的试剂，与α-卤代醛、氨和另一分子羰基化合物（醛或酮）反应，生成3-噻唑啉环系。<ref name="Ariëns">Jürgen Martens, [[Heribert Offermanns]] und Paul Scherberich: ''Eine einfache Synthese von racemischem Cystein'', Angewandte Chemie ''93'' (1981) 680; Angewandte Chemie International Edition English ''20'' (1981) 668.</ref>
