The occurrence of (E)-1-(9-ethyl-9H-carbazol-3-yl)-N-(2-methylindolin-1-yl)methanimine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-1-(9-ethyl-9H-carbazol-3-yl)-N-(2-methylindolin-1-yl)methanimine (CAS 94941-30-7), molecular formula C24H23N3 and molecular weight 353.46 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-1-(9-ethyl-9H-carbazol-3-yl)-N-(2-methylindolin-1-yl)methanimine (C24H23N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 353.46 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
