Antimony hydride, also known as stibine, has the chemical formula SbH3. It is a colorless, flammable gas that is highly toxic and has a characteristic unpleasant odor. Stibine is formed when antimony reacts with certain reducing agents or by the action of certain microorganisms on antimony-containing compounds.

Stibine is highly toxic and poses significant health risks to humans. Inhalation of even small amounts of stibine gas can cause severe health effects, including respiratory irritation, nausea, vomiting, and damage to the lungs, liver, and kidneys. Prolonged exposure or higher concentrations can lead to more severe effects, including convulsions and even death.

Due to its extreme toxicity and potential for explosive decomposition, stibine is not used intentionally in any practical applications. However, it is essential to be aware of its presence in certain industrial processes, such as the production of semiconductors and certain metallurgical operations, where it can be formed as a byproduct.

Safety precautions must be strictly followed when handling antimony compounds or working in environments where stibine may be produced. Proper ventilation, personal protective equipment, and adherence to safety guidelines are crucial to prevent exposure and minimize the risks associated with stibine.
