Tantalum (V) isopropoxide, with the CAS number 16761-83-4, is an organometallic compound of tantalum. It typically appears as a colorless to pale yellow liquid and is known for its hygroscopic nature, meaning it readily absorbs moisture from the air. This compound is primarily used as a precursor in the production of tantalum oxide thin films, which are essential in various applications, including electronics and optics. Tantalum (V) isopropoxide is characterized by its high thermal stability and reactivity, particularly in the presence of water, where it can hydrolyze to form tantalum oxide. It is soluble in organic solvents, such as alcohols and ethers, but insoluble in water. Safety precautions are necessary when handling this compound, as it can be toxic and irritant to the skin and eyes. Proper storage in a dry, inert atmosphere is recommended to prevent degradation and maintain its reactivity for industrial applications.
