2-Cyano-2-(2-oxoindolin-3-ylidene)ethyl acetate CAS 59225-18-2

Description

The occurrence of 2-Cyano-2-(2-oxoindolin-3-ylidene)ethyl acetate 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.

CATO supplies 2-Cyano-2-(2-oxoindolin-3-ylidene)ethyl acetate (CAS 59225-18-2), a certified reference material (molecular formula C13H10N2O3, MW 242.23 g/mol) for analytical method development and quality control.

The molecular framework of 2-Cyano-2-(2-oxoindolin-3-ylidene)ethyl acetate (C13H10N2O3) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures 2-Cyano-2-(2-oxoindolin-3-ylidene)ethyl acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
