Chemical Structure
Description
9,9-Dimethyl-N,N-diphenyl-9H-fluoren-2-amine (CAS 148077-51-4), molecular formula C27H23N and molecular weight 361.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9,9-Dimethyl-N,N-diphenyl-9H-fluoren-2-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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 9,9-Dimethyl-N,N-diphenyl-9H-fluoren-2-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.
