Difucosyllacto-N-neohexaose I is a fluorinated oligosaccharide that was synthesized by click chemistry. The synthesis of this compound involved the addition of a methyl group to the penultimate carbon on the reducing end of a disaccharide. Fluorination was then performed to introduce a trifluoromethyl group onto the sugar ring, which is an important step in obtaining a high level of purity. This compound has been shown to be effective in inhibiting bacterial growth and can be used as an antibacterial agent for prevention and treatment of various infections.

Methyl 2,3,5-tri-O-acetyl-D-arabinofuranoside is a monosaccharide that is used in the synthesis of carbohydrates. It has been shown to inhibit the growth of Rhizopus stolonifer and other fungi. Methyl 2,3,5-tri-O-acetyl-D-arabinofuranoside has also been used for the quantitative analysis of deacetylated sugars. A chromatographic method was developed using an ion exchange resin and methyl glycosides as standards. The sugar was quantified by electron ionization mass spectrometry (EI) after conversion to its trimethylsilyl ether derivatives with triethylamine in methylene chloride. The spectrum obtained from EI analysis showed the presence of anomeric proton peaks at m/z 184 and 186, indicating that this sugar contains two anomeric hydroxyl groups on the same carbon atom.

1,2,3,4,6-Penta-O-acetyl-b-D-galactopyranose, also known as beta-D-galactose pentaacetate, has high chemical stability and long shelf life. This protected form of galactose is a key building block of any chemical synthesis of galactose-containing oligosaccharides or glycoconjugates. In the presence of Lewis acids it can be used as a glycosyl donor to make simple glycosides. In order to perform more complex galactosylations it can be converted into more reactive donors, such as glycosyl halides or thioglycosides.

Methyl 2,3,6-tri-O-benzoyl-a-D-glucopyranoside is a biodegradable polymer that can be used for the prevention of boron diffusion into a prosthesis. It is also resistant to corrosion. Methyl 2,3,6-tri-O-benzoyl-a-D-glucopyranoside has been shown to have a transition temperature of 232 °C and this property makes it suitable for use in high temperature applications. This material is resistant to refractory environments and can be used as an additive in thermodynamic systems.

(S)-3-((2R,3S,5S)-5-Allyl-3-(benzyloxy)-4-oxotetrahydrofuran-2-yl)propane-1,2-diyl dibenzoate is a small molecule that inhibits the activity of the epidermal growth factor receptor (EGFR). The EGFR is a transmembrane protein that binds to and signals through growth factor proteins. Inhibition of EGFR signaling prevents activation of downstream proteins such as extracellular signal regulated kinase 1/2 and phosphatidylinositol 3 kinase. This stabilized form has been shown to inhibit the growth of tumor cells in vitro and in vivo.
