硝普钠
硝普钠又称亚硝基铁氰化钠，化学式：Na2[Fe(CN)5NO]·2H2O，为强有力的血管扩张剂，用于高血压急症和在外科手术时产生控制性低血压，也用于急性心脏衰竭。
由三水合亚铁氰化钾与亚硝酸钠和硫酸反应后，再分别加硫酸铜和碳酸氢钠而得。
硝普盐是化学中已知已久的化合物，它是硝酸与 [Fe(CN)6] 或 [Fe(CN)6] 发生反应时的产物：
![\rm \ [Fe(CN)_6]^{4-}+4H^++NO_3^-\rightarrow [Fe(CN)_5(NO)]^{2-}+CO_2](/uploads/202502/11/e6dca69f6c0b800b9e2e8d6cd276d4224146.png)
Fe(Ⅱ)盐与氰化钾和亚硝酸钠反应也可以得到硝普盐：
![\rm \ [Fe(CN)_6]^{4-}+NO_2^-\rightleftharpoons [Fe(CN)_5(NO_2)]^{4-}+CN^-](/uploads/202502/11/26b75a985a069dcf58b7b68eb0dcd2004146.png)
