(+/-)-Norgnoscopine (3S)-rel-6,7-Dimethoxy-3-[(5R)-5,6,7,8-tetrahydro-4-methoxy-1,3-dioxolo[4,5-g]isoquinolin-5-yl]-1(3H)-isobenzofuranone 36017-64-8 N-Desmethyl Noscapine Nor-|A-gnoscopine Norgnoscopine (CAS 36017-64-8) is a high-purity analytical reference standard with the molecular formula C21H21NO7 and a molecular weight of 399.39 g/mol.

The molecular framework of (+/-)-Norgnoscopine (3S)-rel-6,7-Dimethoxy-3-[(5R)-5,6,7,8-tetrahydro-4-methoxy-1,3-dioxolo[4,5-g]isoquinolin-5-yl]-1(3H)-isobenzofuranone 36017-64-8 N-Desmethyl Noscapine Nor-|A-gnoscopine Norgnoscopine (C21H21NO7) 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).

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.
