Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 636.78 g/mol gives 9-[1,1'-Biphenyl]-3-yl-9'-[1,1'-biphenyl]-4-yl-3,3'-bi-9H-carbazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
9-[1,1'-Biphenyl]-3-yl-9'-[1,1'-biphenyl]-4-yl-3,3'-bi-9H-carbazole (CAS 1643479-47-3), molecular formula C48H32N2 and molecular weight 636.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9-[1,1'-Biphenyl]-3-yl-9'-[1,1'-biphenyl]-4-yl-3,3'-bi-9H-carbazole (C48H32N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
