of double funcitional group of amidogen and sulphonic radical,
may go on chemical reaction with many matters.
--Melting point is 205oC ,decomposing temperature
is 209oC
Use:Metal
parts cleaning,getting away oxidize surface.Slightly corrosive
to metal, usedto flush boiler, and sterilize bacterium in
water.Bleach fibre,wood and paper. Remove nitrite in tobacco.Raw
material for pesticide intermediate,ramification of sulfamic
zcid.
