Chemical Structure
Description
The occurrence of 13-Iodo-2,5,8,11-tetraoxatridecane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
13-Iodo-2,5,8,11-tetraoxatridecane (CAS 143127-81-5), molecular formula C9H19IO4 and molecular weight 318.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 13-Iodo-2,5,8,11-tetraoxatridecane (C9H19IO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
