Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(9,9-Diphenyl-9H-fluoren-2-yl)-N-phenylaniline (CAS 1221237-91-7), molecular formula C37H27N and molecular weight 485.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(9,9-Diphenyl-9H-fluoren-2-yl)-N-phenylaniline (C37H27N) 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).
CATO manufactures 4-(9,9-Diphenyl-9H-fluoren-2-yl)-N-phenylaniline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
