Description
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.
2-(3,4-Dimethylphenyl)-6-((2-hydroxyethyl)amino)-1h-benzo[de]isoquinoline-1,3(2H)-dione (CAS 392670-85-8) is a high-purity analytical reference standard with the molecular formula C22H20N2O3 and a molecular weight of 360.41 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(3,4-Dimethylphenyl)-6-((2-hydroxyethyl)amino)-1h-benzo[de]isoquinoline-1,3(2H)-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.41 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).
As a certified reference material (CRM), 2-(3,4-Dimethylphenyl)-6-((2-hydroxyethyl)amino)-1h-benzo[de]isoquinoline-1,3(2H)-dione 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.
