一般描述
硫代硫酸钠是由硫代硫酸盐和钠离子组成的无机盐，化学式为 Na2S2O3。它是合成化学中常用的还原剂和有用的硫源
应用
应用于广泛使用的、硫代硫酸盐辅助的各种二胺-CuCN配合物合成。
硫代硫酸钠可用作：
- 组分，在水条件下合成不对称芳基硫化物，其中 C-S-C 键在其他两种组分（醇和有机卤化物）环境下形成。
- 活化碳材料的试剂。
- 试剂，使用脱水剂 DMC（2-氯-1,3-二甲基咪唑氯）在水-乙腈溶剂混合物中通过无保护糖的直接缩合合成 S-糖基硫代硫酸盐（糖基硫代盐）。
- 与烷基卤化物一起作为试剂，以 Cu 为催化剂，通过 SN2 机理合成烷基硫代硫酸盐。
- 试剂，通过钯催化交联反应从烷基卤化物合成芳基硫醇。
特点和优势
硫代硫酸钠具有以下特性：
- 稳定
- 环保
- 无臭
- 经济。
