Chemical Structure

SODIUM HYDROGEN SELENITE CAS 7782-82-3 chemical structure

Description

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.

SODIUM HYDROGEN SELENITE (CAS 7782-82-3) is a high-purity analytical reference standard with the molecular formula HO3SeNa and a molecular weight of 150.97 g/mol.

Structurally, SODIUM HYDROGEN SELENITE (HO3SeNa) 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 150.97 g/mol, it falls into the medium-molecular-weight range.

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.
