Chemical Structure
Description
As a certified reference material (CRM), 5-[2-(Benzyloxy)phenyl]-1H-indole-2,3-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.
5-[2-(Benzyloxy)phenyl]-1H-indole-2,3-dione (CAS 893737-56-9) is a high-purity analytical reference standard with the molecular formula C21H15NO3 and a molecular weight of 329.35 g/mol.
The molecular framework of 5-[2-(Benzyloxy)phenyl]-1H-indole-2,3-dione (C21H15NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
