Chemical Structure
Description
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.
Dicyclohexyl(9,10-dihydro-12-phenyl-9,10-ethenoanthracen-11-yl)phosphine (CAS 1166994-77-9), molecular formula C34H37P and molecular weight 476.63 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dicyclohexyl(9,10-dihydro-12-phenyl-9,10-ethenoanthracen-11-yl)phosphine (C34H37P) is characterized by organophosphorus functionality, a polycyclic aromatic system. 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.
