The Antimony trisulfide, with the cas registry number 1345-04-6, has the IUPAC name of sulfanylidene(sulfanylidenestibanylsulfanyl)stibane. This is a kind of yellowish red powder and is insoluble in water and ethylic acid while soluble in concentrated hydrochloric acid, mellow wine, and potassium sulfide solvent. Besides, it is stable but incompatible with acids (reacting to form poisonous hydrogen sulfide), moisture, water, with the product categories including Industrial/Fine Chemicals; Inorganics; Chalcogenides; Materials Science; Metal and Ceramic Science. 

The characteristics of this chemical are as follows: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 0; (5)Exact Mass: 339.724246; (6)MonoIsotopic Mass: 337.723848; (7)Topological Polar Surface Area: 89.5; (8)Heavy Atom Count: 5; (9)Complexity: 34.2; (10)Covalently-Bonded Unit Count: 1.

The production methods of this chemical are below: The first way is treating of trona. The natural trona could be through the process of screening out, smashing and other treating to get this chemical; The second way is antimony white conversion. The natural gray antimony could convert to get this product, with the following equation: Sb₂O₃+4Na₂S+Ca(OH)2+3H₂O→Sb₂S₃+8NaOH+CaS; The third way is direct reaction method: The products could be prepared through the following equation: 3S+2Sb→Sb₂S₃.

As to its usage, it is widely applied in many ways. It could be used in producing safety match, firecracker, munitions, hardening agent or pigment in rubber industry; It could also be used as the analysis reagent and in the preparation of coloured glass.

When you are using this chemical, you should be very cautious. For being a kind of harmful chemical, it may cause damage to health. And it is irritating to eyes, respiratory system and skin and if by inhalation, in contact with skin and if swallowed, it will be dangerous. Therefore, you should take the following advices. Wear suitable protective clothing, gloves and eye/face protection. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

Additionally, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: S=[Sb]S[Sb]=S
(2)InChI: InChI=1S/3S.2Sb
(3)InChIKey: IHBMMJGTJFPEQY-UHFFFAOYSA-N
