Chemical Structure
Description
Based on its molecular formula C48H48N5O3Cl, Rhodanile blue contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 778.39 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).
Rhodanile blue (CAS 14969-56-3), molecular formula C48H48N5O3Cl and molecular weight 778.39 g/mol, is a CATO reference standard with documented purity and traceability.
