2,2'-((Perfluoroethane-1,2-diyl)bis(oxy))bis(2,2-difluoroethan-1-ol) CAS 129301-42-4

Description

The molecular framework of 2,2'-((Perfluoroethane-1,2-diyl)bis(oxy))bis(2,2-difluoroethan-1-ol) (C6H6F8O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.

2,2'-((Perfluoroethane-1,2-diyl)bis(oxy))bis(2,2-difluoroethan-1-ol) (CAS 129301-42-4) is a high-purity analytical reference standard with the molecular formula C6H6F8O4 and a molecular weight of 294.10 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), 2,2'-((Perfluoroethane-1,2-diyl)bis(oxy))bis(2,2-difluoroethan-1-ol) 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.
