Chemical Structure
Description
8-Butyl-5,6-dimethoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline (C16H25NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
8-Butyl-5,6-dimethoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline (CAS 87665-05-2) is a high-purity analytical reference standard with the molecular formula C16H25NO2 and a molecular weight of 263.38 g/mol.
