1,1,1,2,2-Pentafluoro-2-(2-iodo-ethylsulfanyl)-ethane CAS 1206523-87-6

Description

The molecular framework of 1,1,1,2,2-Pentafluoro-2-(2-iodo-ethylsulfanyl)-ethane (C4H4F5IS) is characterized by sulfur-containing functionality, fluorine/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.

1,1,1,2,2-Pentafluoro-2-(2-iodo-ethylsulfanyl)-ethane (CAS 1206523-87-6) is a high-purity analytical reference standard with the molecular formula C4H4F5IS and a molecular weight of 306.04 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.

As a certified reference material (CRM), 1,1,1,2,2-Pentafluoro-2-(2-iodo-ethylsulfanyl)-ethane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
