Abstract: A fluoropolyether group-containing silane compound of the following formula (A1) or (A2). Also disclosed is are surface-treating agent and a pellet including the fluoropolyether group-containing silane compound, and an article including a substrate and a layer on the surface of the substrate formed of fluoropolyether group-containing silane compound. The symbols are as defined in the description.

Abstract: The invention relates to methods of synthesizing 2?-deoxy-2?,2?-difluorotetrahydrouridine with increased purity and uniform particle size distribution. In particular, methods of the invention include crystallization and isolation procedures rendering synthetic reaction intermediates. The invention further includes compositions comprising the final compound in highly pure form, including lower number of impurities and lower levels of individual and total impurities.

Abstract: A surface treating composition is shown and described herein. A surface treating composition comprises (i) a hybrid siloxane oligomer comprises organosilicon units wherein the oligomer comprises organosilicon units with fluoro-functional groups, and organosilicon units with other reactive functionality, and (ii) a perfluoro(poly)ether group containing silane compound. The surface treating composition can be employed to provide a hydrophobic and/or oleophobic surface coating on a surface of a substrate, which may impart other beneficial properties to the article.
