[Chemical Properties]

Leadthiocyanateisawhiteorlightyellow,odorless, crystalline powder. Odorless
[Chemical Properties]

White to yellow powder
[Uses]

Reverse dyeing with aniline black; manufacture of safety matches and cartridges.
[General Description]

A 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.
[Reactivity Profile]

Nitric 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].
[Air & Water Reactions]

Slightly soluble in water.
[Health Hazard]

Early 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.
[Potential Exposure]

An explosive, thermally unstable material. Used in making safety matches, primers for small arms cartridges; pyrotechnic devices; and in dyes.
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.
[Fire Hazard]

Special Hazards of Combustion Products: Irritating sulfur dioxide gas may form in fire.

[Incompatibilities]

Incompatible 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.

[Description]

It 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
