Chemical Structure

Kr-<SUP>82</SUP>Kr CAS 14191-81-2 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.

CATO supplies Kr-<SUP>82</SUP>Kr (CAS 14191-81-2), a certified reference material (molecular formula [82Kr], MW 81.91 g/mol) for analytical method development and quality control.

Structurally, Kr-<SUP>82</SUP>Kr ([82Kr]) 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 81.91 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.
