Chemical Structure
Description
The occurrence of trans-9a-Methyl-5,6,9,9a-tetrahydro-1H-azeto[1,2-a][1,2,3]triazolo[5,1-c]pyrazin-8(9bH)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
trans-9a-Methyl-5,6,9,9a-tetrahydro-1H-azeto[1,2-a][1,2,3]triazolo[5,1-c]pyrazin-8(9bH)-one (CAS 111197-30-9), molecular formula C8H12N4O and molecular weight 180.21 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H12N4O, trans-9a-Methyl-5,6,9,9a-tetrahydro-1H-azeto[1,2-a][1,2,3]triazolo[5,1-c]pyrazin-8(9bH)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 180.21 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).
