Chemical Structure
Description
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.
Ethene, 1,1,2,2-tetrafluoro-, polymer with ethene (CAS 25038-71-5), molecular formula C2F4C2H4 and molecular weight 128.07 g/mol, is a CATO reference standard with documented purity and traceability.
Ethene, 1,1,2,2-tetrafluoro-, polymer with ethene (C2F4C2H4) contains fluorine 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.
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.
