Purpose of ammonium thiocyanate toxicity:

Verify and determine trace amounts of iron, silver, mercury, etc.

It used for the separation of antibiotics, analysis of pesticide content, water quality analysis, preparation of thiocyanate and standard solutions. It is also used for the synthesis of thiocyanates, thiocyanate complex salts, and as a polymerization catalyst.

Safety:

ammonium thiocyanate toxicity has a stimulating effect on the eyes and skin. Rinse with plenty of water to avoid contact with potassium chloride and lead nitrate. Store in a cool and ventilated warehouse, away from direct sunlight. Stay away from sources of fire and heat. Keep the container sealed. It should be stored separately from oxidants and acids.
