Chemical Structure
Description
4,4'-Bis((E)-2-(9-ethyl-9H-carbazol-3-yl)vinyl)-1,1'-biphenyl (CAS 475480-90-1), molecular formula C44H36N2 and molecular weight 592.77 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,4'-Bis((E)-2-(9-ethyl-9H-carbazol-3-yl)vinyl)-1,1'-biphenyl (C44H36N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 592.77 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.
