Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,3,3-Tetramethyl-1,3-bis(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)disiloxane.
1,1,3,3-Tetramethyl-1,3-bis(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)disiloxane (CAS 71363-70-7) is a high-purity analytical reference standard with the molecular formula C20H20F26OSi2 and a molecular weight of 826.50 g/mol.
Based on its molecular formula C20H20F26OSi2, 1,1,3,3-Tetramethyl-1,3-bis(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)disiloxane contains a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 826.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
