Chemical Structure
Description
As a certified reference material (CRM), N-([1,1'-Biphenyl]-2-yl)-9,9-dimethyl-9H-fluoren-3-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
N-([1,1'-Biphenyl]-2-yl)-9,9-dimethyl-9H-fluoren-3-amine (CAS 1421789-39-0) 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 N-([1,1'-Biphenyl]-2-yl)-9,9-dimethyl-9H-fluoren-3-amine (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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
