General description

Hydroxylamine solution is widely used as a reducing agent and antioxidant in organic synthesis, polymer industry and water treatment.

Application

Hydroxylamine solution (NH2OH) can be used as a reactant for the preparation of:
  • Primary amides from aldehydes catalyzed by an arene–ruthenium(II) complex.
  • Hydroxyaminoguanidines and carboxamide derivatives of ofloxacin for biological studies.
  • Fe3O4/Au (GoldMag) nanoparticles for antibody immobilization.

Reactant for preparation of:
  • Prodrug for cardiovascular agent Nω-hydroxy-L-arginine (NOHA, nitric oxide precursor)
  • Hydroxyaminoguanidines as anti-cancer agents
  • Nonsteroidal 2,3-dihydroquinoline glucocorticoid receptor agonists with reduced phosphoenolpyruvate caboxykinase (PEPCK) transactivation
  • Carboxamide derivatives of ofloxacin with improved antimicrobial properties
  • Analogues of coumarin based TNF-α converting enzyme (TACE) inhibitors
  • HIV integrase inhibitors
