2-(1-Methyl-2-oxoindolin-3-ylidene)malononitrile CAS 39081-26-0

Description

The occurrence of 2-(1-Methyl-2-oxoindolin-3-ylidene)malononitrile 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.

2-(1-Methyl-2-oxoindolin-3-ylidene)malononitrile (CAS 39081-26-0), molecular formula C12H7N3O and molecular weight 209.20 g/mol, is a CATO reference standard with documented purity and traceability.

2-(1-Methyl-2-oxoindolin-3-ylidene)malononitrile (C12H7N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 2-(1-Methyl-2-oxoindolin-3-ylidene)malononitrile 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.
