Chemical Structure
Description
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.
(2-bromophenyl)dicyclohexylphosphine 757958-40-0 (CAS 757958-40-0), molecular formula C18H32BrP and molecular weight 359.32 g/mol, is a CATO reference standard with documented purity and traceability.
(2-bromophenyl)dicyclohexylphosphine 757958-40-0 (C18H32BrP) contains organophosphorus functionality, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
