| | Hydrazinium hydroxide solution Usage And Synthesis |
| Chemical Properties | clear colorless solution | | Uses | Hydrazine hydrate may be used to prepare:
- 3-(2-Benzyloxy-6-hydroxyphenyl)-5-styrylpyrazoles by reacting with 5-benzyloxy-2-styrylchromones.
- 3,5-Diphenyl-2-pyrazoline derivatives by reacting with 1,3-diphenyl-2-propen-1-one.
- 3′-Aryl-1,2,3,4,4′,5′-hexahydrospiro[quinoxalin-2,5′-pyrazol]-3-ones by reacting with 3-arylacylidene-3,4-dihydroquinoxalin-2(1H)-ones.
- It may also be used in the catalytic reduction of nitroarenes to aromatic amines.
| | Uses | Hydrazine hydrate solution has been used as a reducing agent for tellurium oxide during the preparation of tellurium nanowires. | | Definition | ChEBI: Hydrazine hydrate is a hydrate. It contains a hydrazine. | | General Description | The addition of hydrazine hydrate to reduced graphene oxide (RGO) counter electrode improves its performance in dye-sensitized solar cells (DSSC). | | Purification Methods | Hydrated hydrazine can be obtained as above and diluted as required. Solutions containing various amounts of H2O are available commercially. |
