Chemical Structure

Sodium Periodate CAS 7790-28-5 chemical structure

Description

Sodium Periodate (CAS 7790-28-5), molecular formula IO4Na and molecular weight 213.89 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Sodium Periodate (IO4Na) contains a salt form, iodine substitution. 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 213.89 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
