The mild and high-yielding synthesis of 18F-labeled aryl trifluoromethyl sulfones, -sulfoxides, and -sulfides using [18F]Ruppert-Prakash reagent is described. The application to the radiolabeling of different bioactive compounds using >1 GBq of 18F-labeling reagent is demonstrated. This work expands the radiochemical space of [18F]CF3-containing structural motifs for the use in positron emission tomography
A method of developing latent prints deposited on a substrate e.g., paper includes impregnating a porous pad with a chemical compound in its solid state which will sublimate preferably within a temperature range of about 100° F. to 300° F. over a short time interval e.g., several minutes with the sublimated gas capable of reacting with one or more of the constituents of latent fingerprint residues to form a visible image of the fingerprint. The pad is placed in a development compartment formed in a base of the apparatus with a heating element located below the pad. The substrate bearing the latent print is placed over the pad. The compartment is closed with a lid and the compound heated to the compound sublimation temperature for a given time to allow the sublimated gas to react with the residue and the substrate is then removed.

A latent fingerprint developing compound is formed by mixing cyanoacrylate, a solvent, and a fluorogenic reagent to provide a homogenous blend. The mixture is then solidified with the mixture having the characteristic of being capable of sublimating at a given temperature and in its sublimated state reacting with one or more of the constituent components of the residue of a latent fingerprint to form a discernable fluorescent image of the print. A latent fingerprint may be developed by exposing a substrate containing the latent print to the sublimated fumes of the compound.

[FR] L'invention concerne un composé de développement d'empreintes digitales latentes, qui est formé par mélange d'un cyanoacrylate, d'un solvant et d'un réactif fluorogène pour fournir un mélange homogène. Le mélange est ensuite solidifié, le mélange ayant la caractéristique d'être capable de se sublimer à une température donnée et, dans son état sublimé, de réagir avec un ou plusieurs des composants constitutifs du résidu d'une empreinte digitale latente pour former une image fluorescente discernable de l'impression. Une empreinte digitale latente peut être développée par exposition d'un substrat contenant l'empreinte latente à des fumées sublimées du mélange.
