Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(4-(Dimethylamino)phenyl)-1-methoxyisoquinolin-5-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
