osmic acid
osmium tetroxide

It is also moderately soluble in water, with which it reacts reversibly to form osmic acid (see below).

Osmic acid, rifampicin and rifamycin (i.e. chemosynovectomy)

A dominant figure in the field of the fine structure of the nervous system, Palay and his colleagues improved the quality of preservation of central nervous tissue by the introduction of a method to fix central nervous tissue by perfusion with osmic acid.

This makes osmium tetroxide the main source of contact with the environment.

This eliminated the need to use osmium tetroxide, which was a rare and expensive chemical.

Examples of such solutes are noble gases and osmium tetroxide.

This dramatically reduces the amount of the highly toxic and very expensive osmium tetroxide needed.

The most common compound exhibiting the +8 oxidation state is osmium tetroxide.

In April 1845, he was poisoned by osmium tetroxide vapors and had to stop working for two weeks.

Osmium tetroxide boils at 130 C and is a powerful oxidizing agent.

The butadiene matrix was stained with osmium tetroxide to provide contrast in the image.

With the asymmetric oxyamination reaction, using osmium tetroxide, being the earliest.

Osmium tetroxide is used in optical microscopy to stain lipids.

It is less volatile than osmium tetroxide.

The Osmium tetroxide molecule is tetrahedral and therefore non-polar.

Osmium tetroxide is often used as a secondary fixative when samples are prepared for electron microscopy.

Osmium powder has the characteristic smell of osmium tetroxide.

The picture was obtained on a thin film of polymer cast onto mercury from solution, and then stained with osmium tetroxide.

It involves the local administration of osmium tetroxide (OsO) which is a highly toxic compound.

Finally, the sections were postfixed with 2% osmium tetroxide, dehydrated and flat embedded in araldite.

Prior to this method, use of stoichiometric amounts of the toxic and expensive osmium tetroxide was often necessary.

Allylic alcohol 29 was oxidized with osmium tetroxide in pyridine to give triol 30.

Finally, the stoichiometric oxidant regenerates the osmium tetroxide - ligand complex (2).

Osmium reacts with oxygen at room temperature forming volatile osmium tetroxide.

Osmium tetroxide can similarly be used to oxidize alkenes to vicinal diols.

The osmium tetroxide is then dissolved in alcoholic sodium hydroxide and separated from the ruthenium tetroxides.

Some stains, such as osmium tetroxide and osmium ferricyanide, are very chemically active.

Thus, Osmium tetroxide is an important oxidizing agent in organic chemistry especially in the conversion of alkenes to 1,2-diols.
