2-(4-Methoxyphenyl)-1H-benzo[de]isoquinoline-1,3(2H)-dione CAS 42340-32-9 chemical structure

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-(4-Methoxyphenyl)-1H-benzo[de]isoquinoline-1,3(2H)-dione (CAS 42340-32-9), molecular formula C19H13NO3 and molecular weight 303.31 g/mol, is a CATO reference standard with documented purity and traceability.

2-(4-Methoxyphenyl)-1H-benzo[de]isoquinoline-1,3(2H)-dione (C19H13NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 2-(4-Methoxyphenyl)-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.
