Chemical Structure
Description
The occurrence of (Iodomethyl)phosphonic acid is closely related to a phosphonate group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(Iodomethyl)phosphonic acid (CAS 13298-02-7), molecular formula CH4IO3P and molecular weight 221.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (Iodomethyl)phosphonic acid (CH4IO3P) is characterized by a phosphonate group, 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.
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.
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.
