Chemical Structure
Description
The occurrence of 6-Methoxy-2-oxoindoline-3-carbaldehyde is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-Methoxy-2-oxoindoline-3-carbaldehyde (CAS 52508-92-6), a certified reference material (molecular formula C10H9NO3, MW 191.18 g/mol) for analytical method development and quality control.
The molecular framework of 6-Methoxy-2-oxoindoline-3-carbaldehyde (C10H9NO3) is characterized by an amino-acid-derived structure, 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).
