Gallium trichloride(CAS: 13450-90-3)

Gallium trichloride, CAS 13450-90-3, is an inorganic compound with the formula GaCl₃. It is a colorless to pale yellow liquid at room temperature with a pungent odor. Gallium trichloride is highly reactive and hygroscopic, forming hydrochloric acid when exposed to moisture.

Gallium trichloride is primarily used in the production of gallium metal and gallium-based alloys. It is also used in semiconductor manufacturing to dope silicon and germanium. Additionally, it serves as a precursor in the synthesis of gallium-containing compounds and in the preparation of gallium-based catalysts.

Gallium trichloride is highly toxic and corrosive. It is classified as a skin and eye irritant. Proper handling requires protective equipment such as gloves, goggles, and a fume hood. Exposure can cause respiratory irritation and damage. Follow safety data sheet (SDS) guidelines and use in a well-ventilated area to minimize risks.

Gallium trichloride should be stored in a tightly sealed, corrosion-resistant container in a cool, dry place away from moisture and heat sources. Store at room temperature or below 25°C to prevent thermal decomposition and formation of hydrochloric acid. Keep away from incompatible materials such as water and alkalis. Handle with care to avoid spillage and ensure proper ventilation during handling to prevent inhalation of fumes.
