Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,2,2-tetrafluoroethene; 1,1,2,2-tetrafluoro-2-[1,1,1,2,3,3-hexafluoro-3-(1,2,2-trifluoroethenoxy)propan-2-yl]oxyethanesulfonyl fluoride 1,1,2,2-tetrakis(fluoranyl)ethene; 1,1,2,2-tetrakis(fluoranyl)-2-[1,1,1,2,3,3-hexakis(fluoranyl)-3-[1,2,2-tris(fluoranyl)ethenoxy]propan-2-yl]oxy-ethanesulfonyl fluoride 925-90-6 A844279.

1,1,2,2-tetrafluoroethene; 1,1,2,2-tetrafluoro-2-[1,1,1,2,3,3-hexafluoro-3-(1,2,2-trifluoroethenoxy)propan-2-yl]oxyethanesulfonyl fluoride 1,1,2,2-tetrakis(fluoranyl)ethene; 1,1,2,2-tetrakis(fluoranyl)-2-[1,1,1,2,3,3-hexakis(fluoranyl)-3-[1,2,2-tris(fluoranyl)ethenoxy]propan-2-yl]oxy-ethanesulfonyl fluoride 925-90-6 A844279 (CAS 925-90-6) is a high-purity analytical reference standard with the molecular formula C2H5BrMg and a molecular weight of 133.27 g/mol.

Owing to a salt form, bromine substitution, 1,1,2,2-tetrafluoroethene; 1,1,2,2-tetrafluoro-2-[1,1,1,2,3,3-hexafluoro-3-(1,2,2-trifluoroethenoxy)propan-2-yl]oxyethanesulfonyl fluoride 1,1,2,2-tetrakis(fluoranyl)ethene; 1,1,2,2-tetrakis(fluoranyl)-2-[1,1,1,2,3,3-hexakis(fluoranyl)-3-[1,2,2-tris(fluoranyl)ethenoxy]propan-2-yl]oxy-ethanesulfonyl fluoride 925-90-6 A844279 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
