Chemical Structure
Description
The occurrence of 6-Chloro-3,3,7-trimethyl-2H-oxazolo[3,2-a]pyrimidin-5(3H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Chloro-3,3,7-trimethyl-2H-oxazolo[3,2-a]pyrimidin-5(3H)-one (CAS 34112-90-8) is a high-purity analytical reference standard with the molecular formula C9H11ClN2O2 and a molecular weight of 214.65 g/mol.
6-Chloro-3,3,7-trimethyl-2H-oxazolo[3,2-a]pyrimidin-5(3H)-one (C9H11ClN2O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
