FAQ
Frequently Asked Questions
It depends on the specific compound and concentration. Some thiocyanates are irritants, while others are relatively low in toxicity. They are generally far less toxic than cyanides.
Cyanate is OCN−, containing oxygen. Thiocyanate is SCN−, where sulfur replaces the oxygen. This change significantly alters its chemical properties.
You are unlikely to encounter it directly. It is used indirectly in processes like textile dyeing, metal cleaning, and as a component in some old photographic chemicals.
It is used diagnostically in tests of thyroid function and kidney clearance. It is also the main detoxification product of cyanide poisoning, so its levels can be clinically measured.
