Description
56013-01-5 Triphenyl[(2,6,6-trimethyl-1-cyclohexen-1-yl)methyl]phosphonium Bromide |A-Cyclogeranyltriphenylphosphonium Bromide (CAS 56013-01-5), molecular formula C28H32PBr and molecular weight 479.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 56013-01-5 Triphenyl[(2,6,6-trimethyl-1-cyclohexen-1-yl)methyl]phosphonium Bromide |A-Cyclogeranyltriphenylphosphonium Bromide (C28H32PBr) is characterized by organophosphorus functionality, bromine substitution, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 56013-01-5 Triphenyl[(2,6,6-trimethyl-1-cyclohexen-1-yl)methyl]phosphonium Bromide |A-Cyclogeranyltriphenylphosphonium Bromide 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.
