(((2-Iodo-1,3-phenylene)bis(oxy))bis(methylene))dibenzene CAS 888968-41-0

Description

(((2-Iodo-1,3-phenylene)bis(oxy))bis(methylene))dibenzene (CAS 888968-41-0), molecular formula C20H17IO2 and molecular weight 416.25 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H17IO2, (((2-Iodo-1,3-phenylene)bis(oxy))bis(methylene))dibenzene contains a steroid core, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 416.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
