Chemical Structure
Description
The occurrence of Tris(2-methoxyphenyl)bismuth dichloride is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tris(2-methoxyphenyl)bismuth dichloride (CAS 121899-81-8) is a high-purity analytical reference standard with the molecular formula C21H21BiCl2O3 and a molecular weight of 601.28 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, Tris(2-methoxyphenyl)bismuth dichloride is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 601.28 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.
