Description

General description

Trimethyl orthoformate is an effective solvent for thallium(III) nitrate-mediated oxidations. It undergoes acid catalyzed reaction with 6-(N-D-ribitylanilino) uracils to form 8-demethyl-8-hydroxy-5-deazariboflavins.

Application

Trimethyl orthoformate was used as dehydrating agent in the preparation of surface-modified colloidal silica nanoparticles.

Surface-modified nanoparticles as a new, versatile, and mechanically robust nonadhesive coating: suppression of protein adsorption and bacterial adhesion.

P F Holmes et al.

Journal of biomedical materials research. Part A, 91(3), 824-833 (2008-12-04)

The synthesis of surface-modified silica nanoparticles, chemically grafted with acrylate and poly(ethylene glycol) (PEG) groups, and the ability of the resulting crosslinked coatings to inhibit protein adsorption and bacterial adhesion are explored.

3D printing of radioactive phantoms for nuclear medicine imaging.

Tilman Läppchen et al.

EJNMMI physics, 7(1), 22-22 (2020-04-24)

For multicenter clinical studies, PET/CT and SPECT/CT scanners need to be validated to ensure comparability between various scanner types and brands. This validation is usually performed using hollow phantoms filled with radioactive liquids. In recent years, 3D printing technology has
