FAQ

What is hydrogen telluride (CAS: 13494-80-9)?

Hydrogen telluride (HTe) is a colorless gas with a garlic-like odor. Its chemical formula is H2Te. Hydrogen telluride is highly reactive and unstable due to the strong Te-H bond. It is a reducing agent and a weak acid in aqueous solution.

What are the main uses of hydrogen telluride (CAS: 13494-80-9)?

Hydrogen telluride is primarily used in the production of tellurium compounds and in semiconductor research. It is also utilized in the synthesis of certain organic compounds and as a reagent in analytical chemistry.

Is hydrogen telluride (CAS: 13494-80-9) safe?

Hydrogen telluride is highly toxic and corrosive. It should be handled in a well-ventilated area with appropriate protective equipment. Storage and handling should comply with local safety regulations and follow Material Safety Data Sheet (MSDS) guidelines. Avoid contact with skin and eyes, and ensure proper ventilation.

How should hydrogen telluride (CAS: 13494-80-9) be stored?

Hydrogen telluride should be stored in a cool, dry, well-ventilated area away from sources of ignition and incompatible materials. It should be stored in a sealed container made of materials such as glass or PFA, and the container should be kept tightly closed to prevent leakage. Avoid exposure to light and maintain a temperature not exceeding 25°C. Handle with care to prevent any spillage or release into the environment.
