Application: | Hydroxylamine hydrochloride can be used as a reactant: • in the synthesis of primary amides from aldehydes in the presence of cesium carbonate (Cs2CO3) as a catalyst. • in the conversion of alicyclic /aliphatic carbonyl compounds and the aromatic aldehydes into corresponding oximes. • in the one-pot synthesis of nitriles from aldehydes in the presence of sodium sulfate (anhyd) and sodium bicarbonate catalysts. • It can also be used as a reducing agent in the preparation of single-layer reduced graphene oxide (RGO) sheets and films. |
Biochem/physiol Actions: | MAO inhibitor; inhibits platelet aggregation. |
