[(3Z)-2-Oxo-1-phenyl-2,3-dihydro-1H-indol-3-ylidene]amino N-ethylcarbamate CAS 866143-52-4 chemical structure

Description

The occurrence of [(3Z)-2-Oxo-1-phenyl-2,3-dihydro-1H-indol-3-ylidene]amino N-ethylcarbamate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

[(3Z)-2-Oxo-1-phenyl-2,3-dihydro-1H-indol-3-ylidene]amino N-ethylcarbamate (CAS 866143-52-4) is a high-purity analytical reference standard with the molecular formula C17H15N3O3 and a molecular weight of 309.32 g/mol.

The molecular framework of [(3Z)-2-Oxo-1-phenyl-2,3-dihydro-1H-indol-3-ylidene]amino N-ethylcarbamate (C17H15N3O3) 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 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.

As a certified reference material (CRM), [(3Z)-2-Oxo-1-phenyl-2,3-dihydro-1H-indol-3-ylidene]amino N-ethylcarbamate 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.
