Chemical Structure

rel-Rac-ethylenebis(indenyl)dimethylzirconium CAS 136844-77-4 chemical structure

Description

rel-Rac-ethylenebis(indenyl)dimethylzirconium (CAS 136844-77-4), molecular formula C20H34C4H12Zr and molecular weight 425.86 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H34C4H12Zr, rel-Rac-ethylenebis(indenyl)dimethylzirconium contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 425.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
