• Verwenden

  Alkylating reagent in mutation research.

• Definition

  ChEBI: A member of the class of 1,4-benzoquinones that is 1,4-benzoquinone in which three of the ring hydrogens are replaced by aziridin-1-yl groups.

• Manufacturing Process

  Under anaerobic conditions including an atmosphere of nitrogen, 104 ml (2.0 moles) of aziridine is added as a single portion with stirring to a suspension of 33.6 g (0.2 mole) of 2,6-dimethoxy-1,4-benzoquinone in 500 ml of absolute methanol at a temperature of 0° to 5°C. After the addition has been 2,6- dimethoxy-1,4-benzoquinone completed the external cooling of the reaction vessel is replaced by a room temperature water bath and the mixture is stirred at room temperature for 45 hours while a slow stream of nitrogen is passed therethrough to preserve the anaerobic reaction conditions. It is found that the yellow starting material, during this period, completely disappears into solution and that a violet or purple substance together with a colorless substance are formed as precipitated reaction products. This mixture of precipitated products is removed by filtration at -20°C and the residue is washed with a small quantity of cooled methanol. Then the mixture is dried in a vacuum desiccator yielding about 30.4 g of mixed product. The mixed product is extracted with benzene whereby the violet or purple colored component passes into solution and the substantially colorless product remains in a yield of about 16.0 g. The colorless 2,6-bis-aziridino-l,4- benzohydroquinone so obtained melts with decomposition at about 221-222°C with melting starting at about 200°C. It can be purified by recrystallization from a of dioxane yielding snow-white crystals that decompose when heated at 222-224°C while starting to melt at 220°C. The benzene extract of the colored reaction product is evaporated to dryness under vacuum, yielding a residue melting at 161-162°C which is recrystallized from 200 ml of ethyl acetate, filtered under suction at -20°C, washed with cold methanol and thus yields about 11.5 g of a pure, purple-colored crystalline 2,3,5-tris-aziridino-1,4-benzoquinone melting at 162.5-163°C.

• Therapeutic Function

  Antineoplastic

• Allgemeine Beschreibung

  Purple needle-like crystals.

• Air & Water Reaktionen

  Slightly soluble in water.

• Reaktivität anzeigen

  trisethyleneiminoquinone is an amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

• Brandgefahr

  Flash point data is not available for trisethyleneiminoquinone, but trisethyleneiminoquinone is probably combustible.

• Sicherheitsprofil

  Poison by intraperitoneal, intravenous, and parenteral routes. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic data. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx. Used as a drug for the treatment of neoplastic dseases.
