| ethylene | <chemical, plant biology> Plant growth substance (phytohormone, plant hormone), involved in promoting growth, epinasty, fruit ripening, senescence and breaking of dormancy. Its action is closely linked with that of auxin. (18 Nov 1997) |
| ethylene chlorohydrin | <chemical> 2-chloroethanol. Used as a solvent, in the manufacture of insecticide, and for treating sweet potatoes before planting. May cause nausea, vomiting, pains in head and chest, stupefaction. Irritates mucous membranes and causes kidney and liver degeneration. Chemical name: Ethanol, 2-chloro- (12 Dec 1998) |
| ethylene diamine tetra acetate | <chemical> A chemical that is used to remove all traces of magnesium and calcium ions from a solution because it binds tightly to them, in order to control unwanted side reactions with these metals during a laboratory process. Acronym: EDTA (11 Nov 1997) |
| ethylene dibromide | <chemical> 1,2-dibromoethane. An effective soil fumigant, insecticide, and nematocide. In humans, it causes severe burning of skin and irritation of the eyes and respiratory tract. Prolonged inhalation may cause liver necrosis. It is also used in gasoline. Members of this group have caused liver and lung cancers in rodents. According to the fourth annual report on carcinogens (ntp 85-002, 1985), 1,2-dibromoethane may reasonably be anticipated to be a carcinogen. Pharmacological action: carcinogens, insecticide. Chemical name: Ethane, 1,2-dibromo- (12 Dec 1998) |
| ethylene dichlorides | Toxic, chlorinated, saturated hydrocarbons. Include both the 1,1- and 1,2-dichloro isomers. The latter is considerably more toxic. It has a sweet taste, ethereal odour and has been used as a fumigant and intoxicant among sniffers. Has many household and industrial uses. (12 Dec 1998) |
| ethylene glycol | <chemical> A common ingredient in anti-freeze, very toxic to the liver if ingested (27 Sep 1997) |
| ethylene glycols | An ethylene compound with two hydroxy groups (-oh) located on adjacent carbons. They are viscous and colourless liquids. Some are used as anaesthetics or hypnotics. However, the class is best known for their use as a coolant or antifreeze. (12 Dec 1998) |
| ethylene oxide | <chemical> Chemical name: Oxirane (12 Dec 1998) |
| ethylene tetrachloride | An anthelmintic against hookworm and other nematodes. Synonym: carbon dichloride, ethylene tetrachloride, tetrachloroethylene. (05 Mar 2000) |
| ethylenebis(dithiocarbamates) | A class of thiocarbamate derivatives whose salts possess fungicidal activity. (12 Dec 1998) |
| ethylenediamine | H2N(CH2)2NH2;a volatile colourless liquid of ammoniacal odour and caustic taste; the dihydrochloride is used as a urinary acidifier. Synonym: ethanediamine. (05 Mar 2000) |
| ethylenediaminetetraacetic acid | (HOOC-CH2)2N(CH2) 2N(CH2-COOH)2;a chelating agent used to remove multivalent cations from solution as chelates, and used in biochemical research to remove Magnesium, Fe2+, etc., from reactions affected by such ions. As the sodium salt, used as a water softener, to stabilise drugs rapidly decomposed in the presence of traces of metal ions, and as an anticoagulant; as the sodium calcium salt, used to remove radium, lead, strontium, plutonium, and cadmium from the skeleton, forming stable un-ionised soluble compounds that are excreted by the kidneys. Compare: EGTA. Synonym: edathamil, edetic acid. Acronym: EDTA (05 Mar 2000) |
| ethylenes | Derivatives of ethylene, a simple organic gas of biological origin with many industrial and biological use. (12 Dec 1998) |
| ethylenethiourea | <chemical> 2-imidazolidinethione. A degradation product of ethylenebis(dithiocarbamate) fungicides. It has been found to be carcinogenic and to cause thyroid hyperplasia. Pharmacological action: carcinogens. Chemical name: 2-Imidazolidinethione (12 Dec 1998) |

| ethanol |
(ethyl alcohol) (C 2 H 6 O; fw 46.07) Commonly used to disinfest plant tissues, glassware utensils and working surfaces in tissue culture manipulations. The concentration used is 70% (v/v) for disinfecting and 95% (v/v) when flaming tools. Ethanol is also used to dissolve water-insoluble additions (addendums) to culture media.
