Chemical Structure

Sodium polytungstate CAS 12141-67-2 chemical structure

Description

Structurally, Sodium polytungstate (O4WO3WNa) contains an inorganic composition. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 502.66 g/mol, it falls into the moderately-high-molecular-weight range.

Sodium polytungstate (CAS 12141-67-2) is a high-purity analytical reference standard with the molecular formula O4WO3WNa and a molecular weight of 502.66 g/mol.

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.
