4,4'-((2,2-Bis((4-iodophenoxy)methyl)propane-1,3-diyl)bis(oxy))bis(iodobenzene) CAS 678187-25-2

Description

Compared with other compounds in its class, the molecular weight of 944.12 g/mol gives 4,4'-((2,2-Bis((4-iodophenoxy)methyl)propane-1,3-diyl)bis(oxy))bis(iodobenzene) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4'-((2,2-Bis((4-iodophenoxy)methyl)propane-1,3-diyl)bis(oxy))bis(iodobenzene) (CAS 678187-25-2), molecular formula C29H24I4O4 and molecular weight 944.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, iodine substitution, 4,4'-((2,2-Bis((4-iodophenoxy)methyl)propane-1,3-diyl)bis(oxy))bis(iodobenzene) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 944.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4,4'-((2,2-Bis((4-iodophenoxy)methyl)propane-1,3-diyl)bis(oxy))bis(iodobenzene) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
