The reaction solution comprises less than 5 mole percent of a nitrogen base. (Formulae I,II)

All nucleotides are the same except for a component called a nitrogen base.

The invention is characterised in that quantities of the nitrogen base of more than 10 wt. % in relation to the organic nitro compound are used.

The slurry comprises less than 5 mole percent of a nitrogen base, and the organic solvent is selected for its low hydrogen chloride solubility.

After removing the excess PC13, a nitrogen base is added to effect condensation of the phosphoromonochloridite with the second aromatic diol to yield the bisphosphite.

A fluorescent nitrogenous base and nucleosides including the fluorescent nitrogenous base are provided.

N,N-dimethylaniline is the preferred nitrogenous base.

Specifically, each nitrogenous base of each filament establishes hydrogen bonds with one and only one nitrogenous base, present on the other filament.

Every nucleotide of both chains possesses a nitrogenous base.

The invention relates to (among other things) oligomer-nitrogenous base conjugates and related compounds.

The compounds are useful for the production of nitrogen mustard prodrugs.

Moreover, this compound further has advantages that nitrogen mustard drugs do not, that is, low toxicity.

A new nitrogen mustard derivative of Formula I or a pharmaceutically acceptable salt thereof, where R is N(CH2CH2Cl)2.

The present invention provides lyophilized pharmaceutical compositions comprising nitrogen mustards; particularly the nitrogen mustard is bendamustine, e.g., bendamustine HCl.

An anti-tumour agent comprises a macromolecular carrier moiety, an active alkylating moiety which is a nitrogen mustard and a stabilising moiety which links the active alkylating moiety with the carrier moiety.

The follow-up of the organic nitrogen and ammonium shows good performances process in the removal of nitrogenous pollution.

The follow-up of the organic nitrogen and ammonium show the good performances of process in elimination of nitrogenous pollution.

This combines a bioreactor with a physical filter in a closed-loop system that eliminated pollution, such as particle compounds, nitrogenous pollution, and organic pollution.

An excessive NH3 excretion contribute to the nitrogen pollution from livestock.

Calculation allowing to highlight areas threatened by nitrogen pollution.

Example of positive side effect of environmental policies primarily aimed at reducing nitrogen pollution

This is occurring in Lake Taupo, the largest lake in the country, which is threatened by nitrogen pollution.

They estimated the annual cost of damage caused by nitrogen pollution across Europe is between 70 to 320 billion euros.
