二硫化物

有机化学中，二硫化物指含有二硫键（-S-S-）的有机硫化合物，具有通式R-S-S-R'。其中的硫氧化态为-1，与过氧化物中的氧类似。

R与R'都为氢（H₂S₂），或有一个为氢（H-S-S-R）时，得到的二硫化物都是不稳定的。但相对于同族多具爆炸性的有机过氧化物，二硫化物稳定性更强，有些多硫化物也是稳定的。

The linkage is also called an SS-bond or a disulfide bridge and is usually derived by the coupling of two thiol groups. In formal terms, the connection is a persulfide, in analogy to its congener, peroxide (R–O–O–R), but this terminology is rarely used, except in reference to hydrodisulfides (R–S–S–H or H–S–S–H compounds).
