Hydroxylamine Sulfate (NH3OH)2SO4, is the sulfuric acid salt of hydroxylamine.
Hydroxylamine Sulfate is primarily used as an easily handled form of hydroxylamine, which is explosive when pure.

Synthesis:
Hydroxylamine Sulfate can be obtained by the acid-base reaction of hydroxylamine with sulfuric acid:
2NH2OH(aq) + H2SO4(aq) → (NH3OH)2SO4(aq)

Applications:
Hydroxylamine Sulfate is used in organic synthesis to convert aldehydes and ketones to oximes, carboxylic acids and their derivatives (e.g. esters) to hydroxamic acids, isocyanates to N-hydroxyureas and nitriles to amidoximes.

Decomposition:
At 120 °C, Hydroxylamine Sulfate begins to decompose to sulfur trioxide, nitrous oxide, water, and ammonia:
2(NH3OH)2SO4 → 2SO3 + N2O + 2NH3 + 5H2O
The reaction is exothermic above 138 °C, and is most exothermic at 177 °C.
