Poison by
intraperitoneal route. Mutation data
reported. A skin, eye, and mucous
membrane irritant. Flammable solid and
combustible liquid when exposed to heat or
flame. To fight fire, use CO2, dry chemical,
or water spray. Explosive reaction with
nitric acid + sulfuric acid above 60°C.
Forms a sensitive explosive mixture with
tetranitromethane. When heated to
decomposition it emits toxic fumes of NOx.

yellow crystalline solid | [Uses]
1-Nitronaphthalene as a nitroaromatic compound is studied for mutagenicity, as nitroaromatics are used in everyday products from polmers, dyes to drugs. | [Uses]
Usually used to study excited state dynamics of 1-nitropthalene in nonpolar, aprotic and protic solvents. | [Definition]
ChEBI: A mononitronaphthalene substituted by a nitro group at position 1. | [Production Methods]
One method to product 1-Nitronaphthalene: Naphthalene is charged to sulfuric acid alternately with mixed acid at 40 – 50 ℃ over 8 h, with the final temperature being 55 ℃. The acid strength used allows the molten product to be separated as an oil and washed. Continuous operation at 50 – 60 ℃ with mixed acid (33/48/19) gives a comparable product. The crude reaction product is obtained in 90 – 95 % yield and is purified by vacuum distillation. | [General Description]
1-Nitronaphthalene is a mutagenic nitroaromatic compound present in diesel exhaust and it causes acute liver and lung toxicity in rodents. 1-Nitronaphthalene is a cytochrome P450-bioactivated, nonciliated bronchiolar epithelial (Clara) cell cytotoxicant . | [Biochem/physiol Actions]
1-Nitronaphthalene binds covalently to protein and forms adducts in the rat airway epithelium in vivo. | [Purification Methods]
Fractionally distil 1-nitronaphthalene under reduced pressure, then crystallise it from EtOH, aqueous EtOH or heptane. Chromatograph it on alumina with *benzene/pet ether as eluent. It sublimes in vacuo. The 1:1 picrate complex has m 72o (from EtOH). [Beilstein 5 H 553, 5 III 1593, 5 IV 1673.] |
