Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 1,4,5,6-tetrahydro-6-oxo-3-pyridazinecarboxylate.
Ethyl 1,4,5,6-tetrahydro-6-oxo-3-pyridazinecarboxylate (CAS 89943-56-6) is a high-purity analytical reference standard with the molecular formula C7H10N2O3 and a molecular weight of 170.17 g/mol.
Based on its molecular formula C7H10N2O3, Ethyl 1,4,5,6-tetrahydro-6-oxo-3-pyridazinecarboxylate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 170.17 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).
