Chemical Structure
Description
The occurrence of Tritylgadolinium(III) chloride is closely related to chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tritylgadolinium(III) chloride (CAS 85906-88-3), molecular formula C19H15Cl2Gd and molecular weight 471.48 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H15Cl2Gd, Tritylgadolinium(III) chloride contains chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 471.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
