Chemical Structure
Description
The occurrence of Chlorotricarbonyl(4,4'-di-t-butyl-2,2'-bipyridine)rhenium(I) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Chlorotricarbonyl(4,4'-di-t-butyl-2,2'-bipyridine)rhenium(I) (CAS 165612-19-1) is a high-purity analytical reference standard with the molecular formula C21H24ClN2O3Re and a molecular weight of 574.09 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Chlorotricarbonyl(4,4'-di-t-butyl-2,2'-bipyridine)rhenium(I) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 574.09 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.
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.
