Chemical Structure

Neon-<SUP>21</SUP>Ne CAS 13981-35-6 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.

Neon-<SUP>21</SUP>Ne (CAS 13981-35-6) is a high-purity analytical reference standard with the molecular formula [21Ne] and a molecular weight of 20.99 g/mol.

Structurally, Neon-<SUP>21</SUP>Ne ([21Ne]) 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 20.99 g/mol, it falls into the low-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.
