Hydroxylamine-O-sulfonic acid Chemical Properties,Usage,Production
Chemical Properties
white to slightly beige crystalline powder
Uses
Hydroxylamine-O-sulfonic acid is used in the synthesis of quinolones for the benzodiazepine site of GABAA receptors. It is also used as a polymerization catalyst and an amination reagent. It is involved in the preparation of diazene by reacting with an alkali. It is also used in the inhibition of polychlorinated dibenzo-p-dioxins (PCDD) as well as (polychlorinated biphenyl) PCB formation in co-combustion.
Uses
Hydroxylamine-O-sulfonic acid (HOSA) may be used to synthesize (Z)-1H-purin-6(7H)-ylideneaminooxysulfonic acid.
HOSA may be used as an aminating reagent in the synthesis of:
- 1-aminotetrazoles and 2-aminotetrazoles
- N-aminopiperidine (NAPP)
- 1H,1′ H-2,2′-biimidazole-1,1′-diamine
General Description
Hydroxylamine-O-sulfonic acid is a versatile synthetic reagent. It is widely employed as a nucleophile and as an electrophile in various organic syntheses. It can be synthesized by reacting hydroxylamine sulfate with 30% fuming H2SO4.
Purification Methods
Stir the solid vigorously with anhydrous Et2O and filter it off using large volumes of dry Et2O. Drain dry at the pump for 5minutes and then for 12-14hours in a vacuum. Store it in a vacuum desiccator over conc H2SO4. Determine the purity by oxidation of iodide to I2. It must be stored in a dry atmosphere at 0-4o. It decomposes slowly in H2O at 25o and more rapidly above this temperature. [Matsuguma & Andrieth Inorg Synth V 122 1957.]
