It is relevant to investigations of antimony compounds, solid-state properties, and semiconductor materials. Its suitability depends on the experimental method and required specifications, while handling must account for its health and environmental hazards.

What is the chemical formula of Antimony Sulphide?

The chemical formula of antimony(III) sulphide is Sb₂S₃, and its empirical formula is also Sb₂S₃ because the atomic ratio cannot be simplified. The compound contains two antimony atoms and three sulphur atoms per formula unit. Its molecular weight is approximately 339.72 g/mol.

What is the CAS number of Antimony Sulphide?

The CAS Registry Number for antimony(III) sulphide is 1345-04-6. This identifier helps distinguish the compound from other antimony sulphides, including antimony(V) sulphide, which has a different chemical composition. Confirming the formula and CAS number helps ensure the correct material is selected for laboratory use.

Is Antimony Sulphide soluble in water?

Antimony(III) sulphide is practically insoluble in water under ordinary conditions. This property is important when selecting solvents or designing sample preparation procedures. Any dissolution or chemical treatment should follow a validated method appropriate for antimony sulphide and should be performed with suitable controls to prevent hazardous exposure and environmental contamination.

How should Antimony Sulphide be stored and handled safely?

Store the material in a tightly closed, compatible, clearly labelled container in a cool, dry, secure location. Avoid generating or inhaling dust, use suitable protective equipment and appropriate ventilation, and prevent environmental release. Follow the current Safety Data Sheet for incompatible materials, spill response, and hazardous waste disposal.

Storage Conditions for Antimony Sulphide

Store Antimony Sulphide in a tightly sealed, compatible, clearly labelled container in a cool, dry, well-ventilated area. Keep it away from strong oxidizing agents, acids, and other incompatible substances identified in the applicable Safety Data Sheet. Secure the container to limit unauthorized access, protect the material from contamination, and prevent dust or residues from entering drains or the environment.

Precautions for Handling Antimony Sulphide

Review the current Safety Data Sheet and complete an appropriate risk assessment before handling Antimony Sulphide. Avoid inhaling dust and prevent skin and eye contact. Wear suitable chemical-resistant gloves, protective clothing, and safety goggles, and use effective local exhaust ventilation when dust may be generated. Avoid release into the environment, collect spills using suitable procedures, and dispose of antimony-containing waste through approved hazardous-waste channels. Use only in appropriately equipped laboratories under trained supervision.
