High purity, submicron and nanopowder forms may be considered. The short answer is “no”, as cyanide poisoning takes place when the cyanide ion binds to iron preventing oxygen uptake by the body's cells. 12.1 Toxicity Toxicity to fish LC50 - Oncorhynchus mykiss (rainbow trout) - > 100 mg/l - 96.0 h Toxicity to daphnia and other aquatic invertebrates EC50 - Daphnia magna (Water flea) - 11 mg/l - 48 h 12.2 Persistence and degradability no data available 12.3 Bioaccumulative potential Toxicity Potassium Thiocyanate (333-20-0) LC50 fish 1 > 100 mg/l EC50 Daphnia 1 11 mg/l 12.2.

Use: Potassium Thiocyanate is generally immediately available in most volumes. Potassium thiocyanate is a potassium salt which is the monopotassium salt of thiocyanic acid. Potassium thiocyanate was used over 50 years ago for the treatment of hypertension and its toxicity appears to cause a neurological disorder consisting of generalized weakness, Also asked, can potassium thiocyanate kill you? Chemical Properties Potassium thiocyanate, KSCN,also known as potassium sulfocyanate and potassium rhodanide, is a colorless deliquescent crystalline solid that melts at 173°C (343 OF) and decomposes at 500°C(932 OF).
