LEAD THIOCYANTE PURE 98%
LEAD THIOCYANTE PURE 98% is a compound, more precisely a salt, with the formula Pb(SCN)2. It is a white crystalline solid, but will turn yellow upon exposure to light.
It is slightly soluble in water and can be converted to a basic salt (Pb(CNS)2·Pb(OH)2 when boiled.
In the early 20th century, thiocyanate was used in the treatment of hypertension, but it is no longer used because of associated toxicity. Sodium nitroprusside, a metabolite of which is thiocyanate, is however still used for the treatment of a hypertensive emergency.
As discussed earlier, thiocyanate is formed from the binding of cyanide and thiosulfate. Thiocyanate is 100-fold less toxic than cyanide and is excreted by the kidney with an approximate elimination half-life of 2.7 days.
Uses. Lead thiocyanate is used in explosives, specifically an ingredient in primers for small-arms cartridges, safety matches, and to reverse aniline black dyeing (Gideon). It can also be used as a precursor for preparing perovskite solar cells.
