Sulphonate

In 1974, Brenner demonstrated that specific gene mutations could be induced in the genome of C. elegans by the chemical compound EMS (ethyl methane sulphonate). ❋ Unknown (2002)

Brenner provided the basis in a publication from 1974, in which he broke new ground by demonstrating that specific gene mutations could be induced in the genome of C. elegans by the chemical compound EMS (ethyl methane sulphonate). ❋ Unknown (2002)

This process proved to be only partially successful as the ligno sulphonate treated area was damaged by pedestrian traffic. ❋ Unknown (1996)

This resulted in testing a process of spraying ligno sulphonate (a chemical binding compound) over the top-surface of the dam, as this was the worst dust source. ❋ Unknown (1996)

The chloride of this compound may again be condensed, for instance, with sodium aminotoluenesulphaminobenzene-sulphonate, and yields the compound -- ❋ Georg Grasser (N/A)

Phthalic acid also is difficult to sulphonate: the sulphonated compound treated with formaldehyde gives only water-insoluble condensation products. ❋ Georg Grasser (N/A)

Among men, researchers found an increase in the likelihood of thyroid disease among those who had high levels of perfluoroctane sulphonate (PFOS) in their blood, but the same association was not found in women. ❋ Unknown (2010)

The anti-HIV gel called PRO 2000 contains a polymer of naphthalene sulphonate designed to physically prevent HIV from binding to cells lining the vagina. ❋ Unknown (2010)

The study included 3966 adults aged 20 and older whose blood serum was sampled between 1999 and 2006 for PFOA and other perfluoroalkyl acid (PFAA) compounds, including perfluoroctane sulphonate (PFOS). ❋ Unknown (2010)
