Air & Water Reactions
Slightly soluble in water.
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].
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.
Fire Hazard
Special Hazards of Combustion Products: Irritating sulfur dioxide gas may form in fire.
Potential Exposure
An explosive, thermally
unstable material. Used in making safety matches, primers
for small arms cartridges; pyrotechnic devices; and in dyes.

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.
Check Digit Verification of cas no
The CAS Registry Mumber 592-87-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 592-87:
(5*5)+(4*9)+(3*2)+(2*8)+(1*7)=90
90 % 10 = 0
So 592-87-0 is a valid CAS Registry Number.

A preparation of lead thiocyanate
Lambou,Dollear
, p. 97 - 101 (1946)
A new and improved method for the preparation of a pure and stable lead thiocyanate in practically theoretical yield has been described. A comprehensive investigation of other published methods has been reported and preparations of lead thiocyanate made by these methods have been compared with the improved compound and various commercial products. All of the products were assayed for purity on the basis of their chemical analyses and tests were made of their capacity for saturating double bonds in cottonseed, peanut, and soybean oils. The lead thiocyanate prepared according to the recommended procedure was found superior to all the other products in stability, purity, and ability to produce dependable and reproducible thiocyanogen values. It has been demonstrated that the ratio of lead ions to thiocyanogen ions and the order of addition of these ions to each other are of major importance in the preparation of pure lead thiocyanate.
Binucleating N624- and 26-Membered Macrocyclic Ligands. Part 2. Transitionmetal Homo- and Hetero-binuclear Complexes: X-Ray Crystallographic Structure Determination of a Lead-Manganese Heterobinuclear Complex

, p. 1001 - 1010 (1988)
Template condensation products of 1,5-diaminopentane and 1,6-diaminohexane with 2,6-diacetylpyridine on Pb(NCS)2 have been transmetallated with CoII and CuII to yield homobinuclear complexes of the 24- and 26-membered macrocycles, L1 and L2 respectively.In the dicobalt(II) complex of the smaller macrocycle, L1, a thermally populated spin equilibrium exists lying well to the low-spin side at 93 K.E.s.r. spectra indicate the complex has an equatorially compressed tetragonal geometry.The dicobalt(II) complex of the larger macrocycle, L2, is effectively high-spin, down to 93 K.Dicopper(II) complexes of L1 display a weak antiferromagnetic interaction, absent in analogous complexes of L2.Heterobinuclear complexes 1(NCS)2(MeCN)2>2 of the 24-membered macrocycle heve been prepared for M = NiII and FeII, as confirmed by fast-atom bombardment (f.a.b.) mass spectra.An X-ray crystallographic structure determination on the heterobinuclear complex PbMnL1(NCS)4 reveals a Pb-Mn distance of 4.857(2) Angstroem and confirms that the metal centres are bridged by two 1,3-μ-NCS-bridges, as inferred from i.r. spectroscopy for the other thiocyanato complexes studied.However, the X-ray structure shows that in this case the thiocyanate bridges present both S-donors to Pb and both N-donors to Mn.
Synthesis and schematic mechanism of 3-phenylamino-4-phenyl-5-tetra-O-acetyl-β-D-glucopyranosylimino-1,2,4-dithiazolidines and Its De-acetylated Nucleoside
Hardas, Aruna,Tayade, Priti
, p. 2310 - 2316 (2018/09/10)
A systematic synthesis of 3-phenylimino-4-phenyl-5-tetra-O-acetyl-β-D-glucopyranosylimino-1,2,4-dithiazolidine (acetylated glucopyranosylimino nucleoside) from glucose as starting material. The steps included acetylating glucose to glucose penta-acetate (II). Step 2 involves the bromination of glucose penta-acetate (II) to 2,3,4,6 tetra-O-acetyl-α-D-glucopyranosyl bromide (III). In step 3 compound (III) reacted with lead thiocyanate to give 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl isothiocyanate (IV). In the step 4 N-phenyl-3-tetra-O-acetyl-β-D-glucopyranosyl isothiocyanate (V) was prepared. In the last step on refluxing compound (V) with N-phenyl S-chloro isothiocarbamoyl chloride to yield acetylated glucopyranosyl nucleoside. Furthermore de-acetylating of acetylated glucopyranosyl nucleoside was carried out to obtain 3-phenylimino-4-phenyl-5-β-D-gluopyranosyl imino 1,2,4-dithiazolidine (de-acetylated glucopyranosylimino nucleoside). The synthesized acetylated glucopyranosylimino nucleoside and deacetylated glucopyranosylimono nucleoside were structurally confirmed by elemental analysis, ultraviolet spectral analysis, infrared spectroscopy, nuclear magnetic resonance spectroscopy and mass spectroscopy.
