Lead niobium potassium oxide CAS 12372-45-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 1158.02 g/mol gives Lead niobium potassium oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Lead niobium potassium oxide (CAS 12372-45-1) is a high-purity analytical reference standard with the molecular formula KNb5O15Pb2 and a molecular weight of 1158.02 g/mol.

Structurally, Lead niobium potassium oxide (KNb5O15Pb2) 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 1158.02 g/mol, it falls into the high-molecular-weight range.

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.
