Chemical Structure
Description
The occurrence of 3-({[(2E)-4-fluoro-3-oxo-1-phenyl-2,3-dihydro-1H-inden-2-ylidene]methyl}amino)benzonitrile is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-({[(2E)-4-fluoro-3-oxo-1-phenyl-2,3-dihydro-1H-inden-2-ylidene]methyl}amino)benzonitrile (CAS 338420-87-4), molecular formula C23H15FN2O and molecular weight 354.38 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-({[(2E)-4-fluoro-3-oxo-1-phenyl-2,3-dihydro-1H-inden-2-ylidene]methyl}amino)benzonitrile (C23H15FN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 354.38 g/mol, it falls into the moderately-high-molecular-weight range. 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.
