Chemical Structure
Description
The occurrence of 5,8-Dimethoxy-2-methyl-N,N-dipropylquinolin-4-amine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5,8-Dimethoxy-2-methyl-N,N-dipropylquinolin-4-amine (CAS 66890-16-2), molecular formula C18H26N2O2 and molecular weight 302.41 g/mol, is a CATO reference standard with documented purity and traceability.
5,8-Dimethoxy-2-methyl-N,N-dipropylquinolin-4-amine (C18H26N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
