2,3,4,6-Tetra-O-acetyl-D-galactopyranosyl azide is a fluorinated sugar that can be used as a synthetic intermediate for the glycosylation of polysaccharides. This compound has been shown to have high purity and does not react with other compounds in the reaction mixture.

2,3,4,6-Tetra-O-acetyl-β-D-mannopyranosyl azide is a crystallographic technique that can be used to determine the structure of molecules. This technique involves the use of x-ray diffraction analysis to produce images of crystal structures. The technique is useful for determining the three dimensional structure of molecules that are too small to be seen with other techniques such as electron microscopy.

Phenyl 2,3,4,6-tetra-O-acetyl-β-D-thioglucopyranoside (PTATG) is a synthetic sugar that is used as a building block in the synthesis of complex carbohydrates. It can be fluorinated to form phenyl 2,3,4,6-tetrafluoro-β-D-thioglucopyranoside (PTFFTG). PTATG and PTFFTG are potential anticancer drugs.

Methyl 2-deoxy-D-ribofuranoside is a methylglucoside that is synthesized by the reaction of thiourea with chloroacetic acid. The anomers of this compound are atypical and the product can be obtained in high yield (70%) by the use of chromatographic purification. This chemical has been used to produce a variety of compounds including carbamates, chloroacetamides, sulfonamides and others. Methyl 2-deoxy-D-ribofuranoside is also an intermediate for asymmetric synthesis. It can act as a catalyst for reactions involving alkali metals and nucleophiles such as chloride, hydantoin and dimethylformamide. The structure of this molecule has been determined by nmr spectroscopy and its 1H NMR spectrum is consistent with that predicted from its molecular formula.

1,2,3,4-Tetra-O-acetyl-L-rhamnopyranose is an acetylated disaccharide that is glycosylated with mercuric triflate and glycoalkaloid acceptors. It has been shown to be a glycosylation coupling agent for theophylline in solanum species. 1,2,3,4-Tetra-O-acetyl-L-rhamnopyranose can also act as a steroidal glycoalkaloid acceptor and has been identified in Solanum species.

Tetra-mannuronic acid sodium salt (β-1,4-linked sodium mannuronotetraose) is one of a number of oligosaccharides obtained from alginate which is a polysaccharide in brown seaweeds containing: blocks of repeating mannuronic acid sequences (M-M-M-M etc), repeating guluronic acid sequences (G-G-G-G etc), and alternating M-G-M-G sequences.  Oligosaccharides can be released using several methods (Lua, 2015; Yanga, 2004) and claims have been published that mannuronic acid oligosaccharides for example, can be effective in the prophylaxis and treatment of Alzheimer's disease, or for the prophylaxis and treatment of diabetes (USP 8835403B2, 2014).

N-(7-Oxadecyl)deoxynojirimycin is a chaperone protein. It belongs to the group of proteins that are deficient in patients with type 1 glycogen storage disease and can be used to treat this condition. N-(7-Oxadecyl)deoxynojirimycin has been shown to bind to the endoplasmic reticulum, thereby preventing the maturation of certain proteins and their transport into other cellular compartments. This agent also has a protective function in muscle cells by preventing protein degradation due to abnormal folding or misfolding. The long-term effect of N-(7-Oxadecyl)deoxynojirimycin on skeletal muscle is unclear, although it has been found to be beneficial in the short term for patients with type 1 glycogen storage disease.

Raloxifene-4'-D-glucuronide D4 lithium salt is a synthetic glycosylate drug, which belongs to the group of anti-estrogens. Raloxifene-4'-D-glucuronide D4 lithium salt is used for the treatment of postmenopausal osteoporosis and prevention of osteoporotic fractures in women with intact uterus. It has been shown to inhibit bone resorption, increase bone mineral density and reduce the incidence of vertebral fractures in postmenopausal women. Raloxifene-4'-D-glucuronide D4 lithium salt can be synthesized using a click chemistry reaction which involves the addition of an azide to an alkyne followed by copper catalysis and subsequent reduction with sodium borohydride. Synthesis of this compound can be achieved without any purification steps due to its high purity.

D-Glucuronic acid (GlcA) is D-glucose with position six oxidised to a carboxyl group (Collins, 2006). It is a common component of a number of gums and mucilages structurally related to pectins, where it is can be present as a terminal non reducing end residue (Renard, 1999). Glucuronic acid is also found in bacterial polysaccharides, such as, xanthan gum produced by Xanthomonas campestris (Faria, 2011), and in glycosaminoglycans, such as, heparan sulfate (Casale, 2020).

Iota-cyclodextrin (ι-CD) contains 14 glucose units. This cyclodextrin has potential applications in host-guest chemistry, particularly for large molecules or assemblies.
