4-((Benzo[d][1,3]dioxol-5-ylimino)methyl)-3-hydroxy-2-(6-methylpyridin-2-yl)isoquinolin-1(2H)-one CAS 565167-37-5 chemical structure

Description

The occurrence of 4-((Benzo[d][1,3]dioxol-5-ylimino)methyl)-3-hydroxy-2-(6-methylpyridin-2-yl)isoquinolin-1(2H)-one 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.

4-((Benzo[d][1,3]dioxol-5-ylimino)methyl)-3-hydroxy-2-(6-methylpyridin-2-yl)isoquinolin-1(2H)-one (CAS 565167-37-5) is a high-purity analytical reference standard with the molecular formula C23H17N3O4 and a molecular weight of 399.40 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 4-((Benzo[d][1,3]dioxol-5-ylimino)methyl)-3-hydroxy-2-(6-methylpyridin-2-yl)isoquinolin-1(2H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 399.40 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).

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.

As a certified reference material (CRM), 4-((Benzo[d][1,3]dioxol-5-ylimino)methyl)-3-hydroxy-2-(6-methylpyridin-2-yl)isoquinolin-1(2H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
