LEAD(II) THIOCYANATE Usage And Synthesis
DescriptionIt has many applications such as phosphorus-free matches, dyeing, and explosives, especially an ingredient in primes for cartridges. Moreover, this chemical can also act as an effective agent for enhancing the performance of perovskite solar cells. For example, planar perovskite solar cells exhibit a reduced hysteresis and boosted fill factor after introducing lead thiocyanate additive.1 Using this additive, the improved performance is further verified in the formamidinium and cesium lead triiodide perovskite solar cells.2 In addition, antigen retrieval can be realized by microwave irradiation in lead thiocyanate.3 Besides, an efficient stereoselective 1,2-dithiocyanation of various alkynes has been accomplished by employing this chemical as a reagent.4

UsesReverse dyeing with aniline black; manufacture of safety matches and cartridges.
UsesLead (II) thiocyanate can be used:
  • To form a complex with Schiff-base lariat crown ether,?N,N′-bis(3-(salicylaldimino)benzyl)-4,13-diaza-18-crown-6.
  • To investigate complexing and fluorescence properties of calixarene bearing two dansyl fluorophores grafted on a large pore mesoporous silica material.
  • As a reagent in the 1,2-dithiocyanation of alkynes in the presence of (dichloroiodo)benzene.
  • As a precursor to synthesize perovskite films for solar cell applications.

General DescriptionA white to yellow crystalline solid. Slightly soluble in water and denser than water. Primary hazard is threat to the environment. Immediate steps should be taken to limit spread to the environment. Used to make explosives, safety matches, and in dyeing.
Air & Water ReactionsSlightly soluble in water.
Reactivity ProfileNitric acid violently oxidized a thiocyanate solution [Bretherick 1979. p. 121]. Caution should be exercised in treating a thiocyanate with an oxidizing agent such as a peroxide or chlorate as such mixtures have been known to explode. May be thermally unstable. Special Hazards of Combustion Products: Irritating sulfur dioxide gas may form in fire [USCG, 1999].
Health HazardEarly symptoms of lead intoxication via inhalation or ingestion are most commonly gastrointestinal disorders, colic, constipation, etc.; weakness, which may go on to paralysis, chiefly of the extensor muscles of the wrists and less often of the ankles, is noticeable in the most serious cases. Ingestion of a laarge amount causes local irritation of the alimentary tract; pain, leg cramps, muscle weakness, paresthesias, depression, coma, and death may follow in 1 or 2 days. Contact causes irritation of eyes and mild irritation of skin.
Fire HazardSpecial Hazards of Combustion Products: Irritating sulfur dioxide gas may form in fire.
Potential ExposureAn explosive, thermally unstable material. Used in making safety matches, primers for small arms cartridges; pyrotechnic devices; and in dyes.
ShippingUN2291 Lead compounds, soluble n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required
IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Contact with acids or acid fumes caused decomposition with fumes of cyanide. Will decompose in hot water.
