Application
Dimethyl sulfate is a powerful methylating reagent for the methylation of carboxylic acids, alcohols, phenols, lactams, oximes, hydroxylamines, and hydroperoxides. It can be used as a reagent for the preparation of N-methyl alkyl- and aryl-substituted amines, amides, and quaternary ammonium salts. Dimethyl sulfate is also used in the methylation of sulfur-containing compounds to synthesize sulfides and sulfonium ions.
It can also be used as a reagent:
It can also be used as a reagent:
- For the preparation of quaternary ammonium acrylic monomer as a potent antibacterial agent by the quaternization of 2-dimethylamino ethyl methacrylate.
- Along with dimethyl sulfoxide for the synthesis of epoxides from aldehydes and ketones via formation of trimethylsulfonium cation.
- To prepare an oxygenate additive for diesel by the methylation of glycerol.

The movement of the small ribosomal subunit (30S) relative to the large ribosomal subunit (50S) during translation is widely known, but many molecular details and roles of rRNA and proteins in this process are still undefined, especially in solution models.

The potential for human disease treatment using human pluripotent stem cells, including embryonic stem cells and induced pluripotent stem cells (iPSCs), also carries the risk of added genomic instability. Genomic instability is most often linked to DNA repair deficiencies, which
