Chemical Structure
Description
Structurally, 4-((5-Chloro-1,3,3-trimethyl-3H-indol-1-ium-2-yl)methylene)-2-((5-(((2,5-dioxopyrrolidin-1-yl)oxy)carbonyl)-1-ethyl-3,3-dimethylindolin-2-ylidene)methyl)-3-oxocyclobut-1-en-1-olate (C34H32ClN3O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 614.09 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
