Chemical Structure
Description
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.
1-(3-((Iodotriphenylphosphoranyl)(methyl)amino)phenyl)ethanone (CAS 88540-73-2), molecular formula C27H25INOP and molecular weight 537.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3-((Iodotriphenylphosphoranyl)(methyl)amino)phenyl)ethanone (C27H25INOP) is characterized by a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, 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.
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.
