Chemical Structure
Description
The molecular framework of (1-Acetamido-2,2-dichlorovinyl)triphenylphosphonium iodide (C22H19Cl2NOPI) is characterized by a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine/iodine substitution. 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.
(1-Acetamido-2,2-dichlorovinyl)triphenylphosphonium iodide (CAS 55630-04-1), molecular formula C22H19Cl2NOPI and molecular weight 542.17 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
