Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
