Dichloramine is a reactive inorganic compound. It has the formula NHCl2. The yellow gas is unstable and reacts with many materials.[1] It is formed by a reaction between ammonia and chlorine or sodium hypochlorite. It is a byproduct formed during the synthesis of chloramine and nitrogen trichloride.

## Synthesis

Dichloramine can be prepared by a reaction between chloramine and chlorine or sodium hypochlorite:[1]

${\displaystyle \mathrm {NH_{2}Cl+Cl_{2}\longrightarrow NHCl_{2}+HCl} }$

## Reaction

Dichloramine reacts with hydroxyl ion, which can be present in water or comes from water molecules, to yield nitroxyl radical and the chloride ion.[2]
