Chemical Structure

Pentaerythrityl tetraiodide CAS 1522-88-9 chemical structure

Description

Pentaerythrityl tetraiodide (CAS 1522-88-9), molecular formula C5H8I4 and molecular weight 575.73 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Pentaerythrityl tetraiodide (C5H8I4) 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.

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.
