CATO supplies 556-56-9 46830QOA4D Allyl iodide 3-Iodopropene 1-Propene, 3-iodo- Propene, 3-iodo- 4-01-00-00761 (Beilstein Handbook Reference) BRN 1697594 EINECS 209-130-4 3-Iodo-1-propene 3-Iodopropylene NSC 18588 UNII-46830QOA4D Allyl iodide [UN1723] [Flammable liquid] UN1723 (CAS 556-56-9), a certified reference material (molecular formula C3H5I, MW 167.98 g/mol) for analytical method development and quality control.
The molecular framework of 556-56-9 46830QOA4D Allyl iodide 3-Iodopropene 1-Propene, 3-iodo- Propene, 3-iodo- 4-01-00-00761 (Beilstein Handbook Reference) BRN 1697594 EINECS 209-130-4 3-Iodo-1-propene 3-Iodopropylene NSC 18588 UNII-46830QOA4D Allyl iodide [UN1723] [Flammable liquid] UN1723 (C3H5I) is characterized by iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
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.
