Based on its molecular formula C5H6N2O, 1H,4H,6H-Furo[3,4-c]pyrazole contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 110.11 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).
CATO supplies 1H,4H,6H-Furo[3,4-c]pyrazole (CAS 4543-55-9), a certified reference material (molecular formula C5H6N2O, MW 110.11 g/mol) for analytical method development and quality control.
