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. It is a precursor to commercial pigments. [1]
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).
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, sometimes simply as lists of synonyms and antonyms.
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.
1,8-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 ...
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.
1,8-Diazafluoren-9-one (DFO) is an aromatic ketone first synthesized in 1950. It is used to find fingerprints on porous surfaces. [1] [2] It makes fingerprints glow when they are lit by blue-green light. [2] DFO reacts with amino acids present in the fingerprint to form highly fluorescent derivatives. Excitation with light at ~470 nm results in ...
1,8-Naphthalic anhydride is an organic compound with the formula C 10 H 6 (C 2 O 3). It is one of three isomers of naphthalic anhydride, the other two being the 1,2- and the 2,3-derivatives. The 1,8-isomer is prepared by aerobic oxidation of acenaphthene. [1] 2,6-naphthalenedicarboxylic acid can be prepared from this anhydride.
