Chemical Structure

2,4,6,8,10-Pentamethyl-2,4,6,8,10-pentakis(3,3,3-trifluoropropyl)cyclopentasiloxane (~90%) CAS 2063-78-7 chemical structure

Description

2,4,6,8,10-Pentamethyl-2,4,6,8,10-pentakis(3,3,3-trifluoropropyl)cyclopentasiloxane (~90%) (C20H35F15O5Si5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
