Chemical Structure
Description
The occurrence of (3E)-1-Methyl-3-[(4-methylphenyl)imino]-2,3-dihydro-1H-indol-2-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3E)-1-Methyl-3-[(4-methylphenyl)imino]-2,3-dihydro-1H-indol-2-one (CAS 73271-41-7) is a high-purity analytical reference standard with the molecular formula C16H14N2O and a molecular weight of 250.30 g/mol.
The molecular framework of (3E)-1-Methyl-3-[(4-methylphenyl)imino]-2,3-dihydro-1H-indol-2-one (C16H14N2O) is characterized by a nitrogen-containing heterocyclic scaffold, 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 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.
As a certified reference material (CRM), (3E)-1-Methyl-3-[(4-methylphenyl)imino]-2,3-dihydro-1H-indol-2-one 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.
