Fluorinated proteins have been synthesized and characterized as potential in vivo 19F magnetic resonance imaging (MRI) and spectroscopy (MRS) agents. Proteins labeled with fluorine include bovine serum albumin, gamma-globulin, and purified immunoglobulin (IgG). The amino groups in proteins were selectively

A 19F-labeled derivative of hen egg-white lysozyme, in which the six epsilon-amino groups are trifluoroacetylated (LF6), was prepared by reaction of lysozyme with S-ethyltrifluorothioacetate. The reaction mixture was fractionated by cation-exchange chromatography at pH 7.3. A comparison of the circular

The molecular structure and conformational properties of S-ethyl trifluorothioacetate, CF(3)COSCH(2)CH(3), were determined in the gas phase by electron diffraction and vibrational spectroscopy (IR and Raman). The experimental investigations were supplemented by ab initio (Moller Plesset of second order) and density
