Compared with other compounds in its class, the molecular weight of 352.84 g/mol gives (2-Methylprop-1-en-1-yl)triphenylphosphonium chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2-Methylprop-1-en-1-yl)triphenylphosphonium chloride (CAS 42855-48-1), molecular formula C22H22PCl and molecular weight 352.84 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2-Methylprop-1-en-1-yl)triphenylphosphonium chloride (C22H22PCl) is characterized by organophosphorus functionality, chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (2-Methylprop-1-en-1-yl)triphenylphosphonium chloride 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.
