Picture Example:

Sodium Dithionite Hyposulfite 88 90 Crystalline Powder

Aqueous solutions of sodium dithionite were once used to produce 'Fieser's solution' for the removal of oxygen from a gas stream.Pyrithione can be prepared in a two-step synthesis from 2-bromopyridine by oxidation to the N-oxide with a suitable peracid followed by substitution using sodium dithionite to introduce the thiol functional group.

◎Chemical Name: Sodium hydrosulphite

◎Chemical Formula：Na2S2O4
◎CAS No.:7775-14-6
◎Appearance:Free-flowing white crystalline powder
◎Odor:Odorless or with a slight odor of sulfur dioxide

Sodium hydrosulfite redirects here. For sodium hydrogen sulfite (NaHSO3), sometimes erroneously referred to as sodium hydrosulfite, see Sodium bisulfite.

Sodium dithionite (also known as sodium hydrosulfite) is a white crystalline powder with a sulfurous odor. Although it is stable in dry air, it decomposes in hot water and in ACID solutions.
