What is dimethyl alpha naphthylamine?
Biochem/physiol Actions. N,N-Dimethyl-1-naphthylamine (1-Dimethylaminonaphthalene) is used to study nitrate reduction by organisms. Reduction of nitrate results in the formation of nitrite, which reacts with sulfanilic acid and 1-dimethylaminonaphthalene to form a red diazo dye.
Does 1 naphthylamine dissolve in water?
3.2.1Physical Description Alpha-naphthylamine appears as a crystalline solid or a solid dissolved in a liquid. Insoluble in water and denser than water. Contact may slightly irritate skin, eyes and mucous membranes.

Is naphthalene an amine?
1-Naphthylamine is an aromatic amine derived from naphthalene. It can cause bladder cancer (transitional cell carcinoma). It crystallizes in colorless needles which melt at 50 °C. It possesses a disagreeable odor, sublimes readily, and turns brown on exposure to air.
What is naphthylamine used for?
2-Naphthylamine is now used only in laboratory research. It formerly was used commercially as an intermediate in the manufacture of dyes, as an antioxidant in the rubber industry, and to produce 2-chloronaphthylamine (IARC, 1974; HSDB, 2003).
Where is naphthylamine found?
2-Naphthylamine DNA adducts have been found in bladder and liver cells from exposed dogs (IARC 1987). 2-Naphthylamine is an aromatic amine (arylamine) that exists at room temperature as colorless crystals with a faint aromatic odor.
Is acetophenone a liquid or solid?
Pure acetophenone is a colourless liquid, with a melting point of 20.2 °C (68.4 °F) and a boiling point of 202.4 °C (396.3 °F). It is only slightly soluble in water but is freely soluble in ethanol (ethyl alcohol), diethyl ether, and chloroform.
Is naphthalene an atom?
naphthalene, the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms; chemical formula, C10H8.
Is naphthylamine a carcinogen?
2-Naphthylamine is known to be a human carcinogen based on suffi- cient evidence of carcinogenicity from studies in humans. Epidemiological studies have shown that occupational exposure to 2-naphthylamine, either alone or present as an impurity in other compounds, causes cancer of the urinary bladder.
Does benzene cause leukemia?
Long-term exposure to high levels of benzene in the air can cause leukemia, cancer of the blood-forming organs.
Is hydroquinone a phenol?
Hydroquinone, also known as benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C6H4(OH)2. It has two hydroxyl groups bonded to a benzene ring in a para position. It is a white granular solid.
What is NN-phenyl-1-naphthylamine?
N-Phenyl-1-naphthylamine’s production and use as an antioxidant in various lubrication oils and as both a protective agent and antioxidant in rubber and rubber mixtures for various products, including tires, may result in its release to the environment thorugh various waste streams.
Is N-phenyl-2-naphthylamine metabolized in humans?
In studies conducted with human volunteers or laboratory animals, the isomer N-phenyl-2-naphthylamine was partially metabolized to the known human carcinogen 2-naphthylamine following ingestion or inhalation.
What are the side effects of N-phenyl-1-naphthylamine?
The oral administration of 200 mg N-phenyl-1-naphthylamine/kg bw/day, 5 days/wk for 6 weeks, resulted in diarrhea, proteinuria, slight irritation of the kidneys, and a fatty degeneration of the liver.
What is the Henry’s Law constant for N-phenyl-1-naphthylamine?
The Henry’s Law constant for N-phenyl-1-naphthylamine is estimated as 1.4X10-7 atm-cu m/mole(SRC) derived from its vapor pressure, 1.13X10-5 mm Hg(1), and water solubility, 60 mg/L(2). This Henry’s Law constant indicates that N-phenyl-1-naphthylamine is expected to be essentially nonvolatile from water surfaces(3).
