[(3Z)-2-Oxo-1-phenyl-2,3-dihydro-1H-indol-3-ylidene]amino 2-methylpropanoate CAS 478261-20-0

Description

The occurrence of [(3Z)-2-Oxo-1-phenyl-2,3-dihydro-1H-indol-3-ylidene]amino 2-methylpropanoate 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 2-methylpropanoate (CAS 478261-20-0) is a high-purity analytical reference standard with the molecular formula C18H16N2O3 and a molecular weight of 308.33 g/mol.

The molecular framework of [(3Z)-2-Oxo-1-phenyl-2,3-dihydro-1H-indol-3-ylidene]amino 2-methylpropanoate (C18H16N2O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
