3-Nitrobenzanthrone (3-nitro-7H-benz[de]anthracen-7-one) is a chemical compound emitted in diesel exhaust; it is a potent carcinogen. [2] It produced the highest score ever reported in the Ames test, a standard measure of the cancer-causing potential of toxic chemicals, far greater than the previous known strongest (1,8-dinitropyrene, which is also found in diesel exhaust).
1,8-Diaminonaphthalene is an organic compound with the formula C 10 H 6 (NH 2) 2. It is one of several isomeric naphthalenediamines . It is a colorless solid that darkens in air due to oxidation.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
1,8-Naphthyridine is an organic compound with the formula C 8 H 6 N 2. It is the most well-studied of the six isomeric naphthyridines, a subset of diazanaphthalenes with nitrogen in the separate rings. [2] [3] Enoxacin, nalidixic acid, and trovafloxacin are 1,8-naphthyridine derivatives with antibacterial properties related to the ...
The aromatization of an additional ring in 4,12-Dihydrogen-4,8,12-triazatriangulene is utilized by Al-Yassiri and Puchta to get a representative for a new class of Δ-shaped proton sponges. [8] This compound has a calculated proton affinity of 254 kcal/mol (B3LYP/6-311+G**) and is therefore between 1,8-Bis(dimethylamino)naphthalene and HMPN.
1-Nitropyrene is a by-product of combustion and is the predominant nitrated polycyclic aromatic hydrocarbon emitted in a diesel engine. [ 1 ] 1-Nitropyrene is listed as an IARC Group 2B carcinogen , [ 2 ] indicating it is possibly carcinogenic to humans.
Thesaurus Linguae Latinae. A modern english thesaurus. A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms ...
In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. [1] For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called Pinus abies .
