Antimony Trioxide – 500 gram Packs

Antimony Trioxide, also known as antimony(III) oxide or diantimony trioxide, is an inorganic oxide of antimony with the chemical formula Sb₂O₃. It has a molecular weight of approximately 291.52 g/mol and is identified by CAS Number 1309-64-4. This compound is commonly encountered as a white crystalline powder and is only sparingly soluble in water. Its chemical properties make it relevant to inorganic chemistry, analytical investigations, and research involving antimony-containing compounds and solid-state materials. In laboratory settings, Antimony Trioxide can be used in selected studies of metal oxides, chemical reactions, and material characterization, provided its specifications are appropriate for the intended procedure. It is also important in research examining the behaviour of antimony(III) compounds under controlled conditions. This Laboratory Reagent is offered in a 500 gram pack format for suitable institutional and research requirements. Because inhalation of its dust may present significant health risks, appropriate exposure controls and safe handling procedures are essential.

Frequently Asked Questions About Antimony Trioxide

What is Antimony Trioxide used for in laboratories?

Antimony Trioxide is used in selected inorganic chemistry and materials research involving antimony oxides and related compounds. It may serve as a starting material in suitable preparation studies or as a reagent in procedures that specifically require it. Its suitability depends on the experimental method, required specifications, and appropriate safety controls.

What is the chemical formula of Antimony Trioxide?

The chemical formula of Antimony Trioxide is Sb₂O₃, and its empirical formula is also Sb₂O₃ because the atom ratio cannot be reduced further. The compound contains two antimony atoms and three oxygen atoms per formula unit. Its molecular weight is approximately 291.52 g/mol.

What is the CAS number of Antimony Trioxide?

The CAS Registry Number for antimony(III) oxide is 1309-64-4. This identifier helps distinguish the compound from other antimony oxides and salts. Confirming the CAS number alongside the chemical formula is important when selecting reagents for laboratory experiments, analytical procedures, or research applications.

Is Antimony Trioxide soluble in water?

Antimony Trioxide has very low solubility in water under ordinary conditions. Its behaviour can depend on the medium and experimental conditions, so complete dissolution should not be assumed during sample preparation. Laboratories should follow an appropriate validated method and avoid procedures that could create uncontrolled exposure to antimony-containing dust.

How should Antimony Trioxide be stored and handled safely?

Store the material in a tightly closed, clearly labelled container in a secure, dry, well-ventilated location. Avoid generating or inhaling dust and use suitable protective gloves, eye protection, and effective local exhaust ventilation. Follow the current Safety Data Sheet for handling precautions, spill response, and hazardous waste disposal.

Storage Conditions for Antimony Trioxide

Store Antimony Trioxide in a tightly sealed, compatible, clearly labelled container in a cool, dry, well-ventilated area. Protect the material from contamination and prevent dust from accumulating around the storage location. Keep it securely stored with access restricted to trained personnel, and segregate it from incompatible substances identified in the applicable Safety Data Sheet.

Precautions for Handling Antimony Trioxide

Review the current Safety Data Sheet and complete an appropriate risk assessment before handling Antimony Trioxide. Avoid inhaling dust and prevent unnecessary skin and eye contact. Wear suitable protective gloves, safety goggles, and laboratory clothing, and use effective local exhaust ventilation during dusty operations. Prevent environmental release and follow established procedures for spill management and hazardous waste disposal. Because repeated dust exposure may present serious health concerns, use this compound only in appropriately equipped laboratories with suitable exposure controls.
