Rhenium(VI) oxide CAS 1314-28-9 chemical structure

Description

Rhenium(VI) oxide (CAS 1314-28-9), molecular formula O3Re and molecular weight 234.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Rhenium(VI) oxide (O3Re) 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 234.21 g/mol, it falls into the medium-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.
