Tantalum(V) ethoxide, 99.98%

About Tantalum(V) ethoxide, 99.98%

Tantalum(V) ethoxide is an organometallic reagent carrying the CAS registry number 6074-84-6 at a purity of 99.98%. Its molecular formula is C10H25O5Ta and its molecular weight is 406.25 g/mol. Systematically, it is named ethanolate. Tantalum(5+). It is also known as Tantalum(V) ethylate or Tantalum(5+) ethanolate.

It is supplied as a liquid. Key physical data: a melting point of 21 °C and a boiling point of 155 °C. Store in a cool, well-ventilated place, away from sources of ignition, with the container tightly sealed. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for carbon–carbon bond formation, grignard and organometallic chemistry, organic synthesis and nanotechnology research. Buyers come mainly from academic and industrial research.

Standard pack sizes are 10 g and 100 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
