Chemical Structure
Description
The occurrence of 3-(3,4-Dimethoxyphenyl)-6,7,8-trimethoxy-1-methylisoquinoline is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(3,4-Dimethoxyphenyl)-6,7,8-trimethoxy-1-methylisoquinoline (CAS 113021-57-1), molecular formula C21H23NO5 and molecular weight 369.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(3,4-Dimethoxyphenyl)-6,7,8-trimethoxy-1-methylisoquinoline (C21H23NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
