Chemical Structure
Description
5-[(4-nitro-1h-pyrazol-1-yl)methyl]furan-2-carbaldehyde (C9H7N3O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
