1,1'-(((Oxybis(ethane-2,1-diyl))bis(oxy))bis(2,1-phenylene))bis(ethan-1-one) CAS 89579-20-4

Description

1,1'-(((Oxybis(ethane-2,1-diyl))bis(oxy))bis(2,1-phenylene))bis(ethan-1-one) (CAS 89579-20-4) is a high-purity analytical reference standard with the molecular formula C20H22O5 and a molecular weight of 342.39 g/mol.

Structurally, 1,1'-(((Oxybis(ethane-2,1-diyl))bis(oxy))bis(2,1-phenylene))bis(ethan-1-one) (C20H22O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 342.39 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
