Chemical Structure
Description
Dicyclohexyl(9-butylfluoren-9-yl)phosphonium tetrafluoroborate (CAS 1007311-98-9), molecular formula C29H40PBF3F and molecular weight 506.41 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system, Dicyclohexyl(9-butylfluoren-9-yl)phosphonium tetrafluoroborate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 506.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
