Chemical Structure
Description
2-(2-Aminoethyl)-5,6-dimethylthieno[2,3-d]pyrimidin-4(3H)-one hydrochloride (C10H13N3OSHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
