Chemical Structure

Tantalum silicide (99.5%-Ta) CAS 12039-79-1 chemical structure

Description

The occurrence of Tantalum silicide (99.5%-Ta) is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tantalum silicide (99.5%-Ta) (CAS 12039-79-1), molecular formula Si2Ta and molecular weight 237.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an inorganic composition, Tantalum silicide (99.5%-Ta) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
