Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 441.89 g/mol gives Tantalum(V) oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tantalum(V) oxide (CAS 1314-61-0), a certified reference material (molecular formula O5Ta2, MW 441.89 g/mol) for analytical method development and quality control.
Based on its molecular formula O5Ta2, Tantalum(V) oxide contains an inorganic composition; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 441.89 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
