3-Oxo-4-(1,3,3-trimethylindolin-2-ylidene)butanenitrile CAS 97214-25-0

Description

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.

3-Oxo-4-(1,3,3-trimethylindolin-2-ylidene)butanenitrile (CAS 97214-25-0), molecular formula C15H16N2O and molecular weight 240.30 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H16N2O, 3-Oxo-4-(1,3,3-trimethylindolin-2-ylidene)butanenitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
