Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 361.48 g/mol gives 2-[(4-Biphenylyl)amino]-9,9-dimethylfluorene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-[(4-Biphenylyl)amino]-9,9-dimethylfluorene (CAS 897671-69-1) is a high-purity analytical reference standard with the molecular formula C27H23N and a molecular weight of 361.48 g/mol.
The molecular framework of 2-[(4-Biphenylyl)amino]-9,9-dimethylfluorene (C27H23N) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
