Textile: printing, dyeing and finishing operations accelerator in fixing baths
Pesticide: raw material for the production of a number of herbicides and fungicides
Photographit: Stabilizer, accelerator, etc.
Metal finishing: Plating, flotation agent.
as intermediate for metal thiocyanates (NaSCN, KSCN, CuSCN, Ca(SCN)2 ).
