Description

 

Hydroxylamine is an inorganic compound. It is used to prepare oximes, an important functional group. It is also an intermediate in biological nitrification. Hydroxylamine and its salts are commonly used as reducing agents in a myriad of organic and inorganic reactions. They can also act as antioxidants for fatty acids. Some non-chemical uses include removal of hair from animal hides and photography developing solutions. It is used as an irreversible inhibitor of the oxygen-evolving complex of photosynthesis on account of its similar structure to water. In the semiconductor industry, hydroxylamine is often a component in the "resist stripper" which removes photoresist after lithography.
