Chemical Structure

1-Chloro-2-iodotetrafluoroethane CAS 421-78-3 chemical structure

Description

1-Chloro-2-iodotetrafluoroethane (C2ClF4I) contains fluorine/chlorine/iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

1-Chloro-2-iodotetrafluoroethane (CAS 421-78-3) is a high-purity analytical reference standard with the molecular formula C2ClF4I and a molecular weight of 262.37 g/mol.

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.
