Chemical Structure
Description
Methyl 6-chloro-2-oxo-2,3-dihydro-1H-pyrrolo[2,3-b]pyridine-4-carboxylate (C9H7ClN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
