Denatured Alcohol

Denatured alcohol is ethanol that has additives to make it undrinkable (poisonous), to prevent human consumption. In some cases it is also dyed. Denatured alcohol is used as a solvent and as fuel for spirit burners and camping stoves. Because of the diversity of industrial uses for denatured alcohol, hundreds of additives and denaturing methods have been used. The main additive has traditionally been 10% methanol, giving rise to the term "methylated spirit." Other typical additives include isopropyl alcohol, acetone, methyl ethyl ketone, methyl isobutyl ketone, and denatonium. Denaturing alcohol does not chemically alter the ethanol molecule. Rather, the ethanol is mixed with other chemicals to form an undrinkable solution. Different additives are used to make it difficult to use distillation or other simple processes to reverse the denaturation. Methanol is commonly used both because its boiling point is close to that of ethanol and because it is toxic. In many countries, it is also required that denatured alcohol be dyed blue or purple with an aniline dye.

Dendrimer

Dendrimers are repetitively branched molecules. The name comes from the Greek word "δένδρον" (pronounced dendron), which translates to "tree". Synonymous terms for dendrimer include arborols and cascade molecules. However, dendrimer is currently the internationally accepted term. A dendrimer is typically symmetric around the core, and often adopts a spherical three-dimensional morphology. The word dendron is also encountered frequently. A dendron usually contains a single chemically addressable group called the focal point. Applications of dendrimers typically involve conjugating other chemical species to the dendrimer surface that can function as detecting agents (such as a dye molecule), affinity ligands, targeting components, radioligands, imaging agents, or pharmaceutically active compounds. Dendrimers have very strong potential for these applications because their structure can lead to multivalent systems. Dendrimers can also be used as a solubilizing agent. Since their introduction in the mid-1980s, this novel class of dendrimer architecture has been a prime candidate for hosts guest chemistry. Dendrimers with hydrophobic core and hydrophilic periphery have shown to exhibit micelle-like behavior and have container properties in solution. The use of dendrimers as unimolecular micelles was proposed by Newkome in 1985. This analogy highlighted the utility of dendrimers as solubilizing agents. The majority of drugs available in pharmaceutical industry are hydrophobic in nature and this property in particular creates major formulation problems

Dess-Martin Periodinane

The Dess-Martin periodinane (DMP) is commercially available and decomposes only slowly. But DMP is heat- and shock-sensitive, and shows an exotherm when heated >130 °C. 2-Iodoxybenzoic acid (IBX), the impact-sensitive intermediate in the synthesis of the Dess-Martin periodinane, is available in a DMSO solution and is also used as an oxidizing agent.

Dextrose

Dextrose is a simple sugar and an important carbohydrate in biology. Cells use it as the primary source of energy and a metabolic intermediate. It is one of the main products of photosynthesis and starts cellular respiration. It is a common medical analyte measured in blood samples. In industry, dextrose is used as a precursor to make vitamin C in the Reichstein process, to make citric acid, gluconic acid, bio-ethanol, polylactic acid, sorbitol.
