Application
Dimethyl sulfate may be used along with alumina for preparation of monomethylated derivatives of alcohols, phenols and carboxylic acids. It may also be used in combination with dimethylformamide (DMF) to form methoxy-methylene-N,N-dimethyliminium salt, that can be utilized for the preparation of β-lactams.

Prevailing dogma holds that ribosomes are uniform in composition and function. Here, we show that nutrient limitation-induced stress in E. coli changes the relative expression of rDNA operons to alter the rRNA composition within the actively translating ribosome pool. The most

The physical properties of polyaniline (PAn) powder, doped by nucleophilic doping of dimethyl sulfate (DMS), were characterized, as well as its electrochemical behaviors, to investigate the possibility of a power source device adopting the PAn-DMS electrodes. It is shown that
