4-(3-Hydroxy-4-methoxybenzyl)-7-methoxyisoquinolin-8-ol CAS 21628-67-1

Description

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 4-(3-Hydroxy-4-methoxybenzyl)-7-methoxyisoquinolin-8-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

4-(3-Hydroxy-4-methoxybenzyl)-7-methoxyisoquinolin-8-ol (CAS 21628-67-1), molecular formula C18H17NO4 and molecular weight 311.33 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
