Description

Compared with other compounds in its class, the molecular weight of 618.24 g/mol gives 2,2'-((((2,5-Diiodo-1,4-phenylene)bis(oxy))bis(ethane-2,1-diyl))bis(oxy))bis(tetrahydro-2H-pyran) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,2'-((((2,5-Diiodo-1,4-phenylene)bis(oxy))bis(ethane-2,1-diyl))bis(oxy))bis(tetrahydro-2H-pyran) (CAS 1956377-70-0), a certified reference material (molecular formula C20H28I2O6, MW 618.24 g/mol) for analytical method development and quality control.

The molecular framework of 2,2'-((((2,5-Diiodo-1,4-phenylene)bis(oxy))bis(ethane-2,1-diyl))bis(oxy))bis(tetrahydro-2H-pyran) (C20H28I2O6) is characterized by a steroid core, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
