Description

Compared with other compounds in its class, the molecular weight of 274.32 g/mol gives (2E)-2-[(Pyridin-3-yl)methylidene]-2,3,4,9-tetrahydro-1H-carbazol-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2E)-2-[(Pyridin-3-yl)methylidene]-2,3,4,9-tetrahydro-1H-carbazol-1-one (CAS 866138-46-7) is a high-purity analytical reference standard with the molecular formula C18H14N2O and a molecular weight of 274.32 g/mol.

The molecular framework of (2E)-2-[(Pyridin-3-yl)methylidene]-2,3,4,9-tetrahydro-1H-carbazol-1-one (C18H14N2O) is characterized by a steroid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
