N-Nitrosodiphenylamine is an industrial compound.
N-Nitrosodiphenylamine is an orange-brown or yellow solid that has been produced since 1945.
N-Nitrosodiphenylamine is a member of phenylhydrazines.
N-Nitrosodiphenylamine is an industrial chemical.
N-Nitrosodiphenylamine is an orange-brown or yellow solid that was first manufactured in 1945.
N-Nitrosodiphenylamine is used to make rubber products, such as tires, or to make other chemicals.
N-Nitrosodiphenylamine is used to make rubber products such as tires or to make other chemicals.
In the early 1980s, most U.S. rubber manufacturers replaced N-Nitrosodiphenylamine with more efficient chemicals.
Today, only one manufacturer in the United States produces N-Nitrosodiphenylamine.
N-Nitrosodiphenylamine appears as yellow to brown or orange powder or flakes or a black solid. Insoluble in water and denser in water. Hence sinks in water.
In the early 1980s, most U.S. rubber manufacturers replaced N-Nitrosodiphenylamine with other chemicals.
In 2016, only one facility in the United States was manufacturing and processing of N-Nitrosodiphenylamine.
N-Nitrosodiphenylamine can enter the environment from waste sites.
N-Nitrosodiphenylamine usually breaks down in air, water, and soil within several weeks.
In soil and water, N-Nitrosodiphenylamine is broken down by bacteria.
N-Nitrosodiphenylamine will dissolve in water but sticks strongly to soil and does not move quickly through it.
N-Nitrosodiphenylamine is a disinfection by product in drinking water.
N-Nitrosodiphenylamine is not known what governs the formation of NDPhA and which precursor(s) in the raw water is responsible for its formation.
N-Nitrosodiphenylamine is reported here diphenylamine (DPhA) as a key precursor of N-Nitrosodiphenylamine, and we describe the effect of water pH and chloramination conditions on the formation of NDPhA.
To identify precursors of N-Nitrosodiphenylamine, raw water samples were collected from the same drinking water system in which NDPhA was previously detected.
Analysis of the raw water samples showed the presence of 1.3 ng/L of DPhA and no detectable N-Nitrosodiphenylamine.
N-Nitrosodiphenylamine may be sensitive to moisture at elevated temperatures in strongly acidic solutions.
N-Nitrosodiphenylamine may react vigorously with oxidizing agents.
N-Nitrosodiphenylamine may undergo trans-nitrosation reactions with secondary amines.
N-Nitrosodiphenylamine is a yellow to orangebrown crystalline solid.
N-Nitrosodiphenylamine is a yellow to brown or orange powder or flake.
N-Nitrosodiphenylamine was used in making rubber products such as tires and tools.
N-Nitrosodiphenylamine is no longer produced in the United States.
N-Nitrosodiphenylamine can also be used to validate appropriate test methods or qualify an instrument in a regulated industry.
N-Nitrosodiphenylamine is tested on a high performance GC-MS.
N-Nitrosodiphenylamine is prepared gravimetrically on a weight/volume basis to a specification of ± 2.5%.
The concentration of each standard is verified using a high performance calibrated Gas Chromatograph, Mass Spectrometer (GC-MS Instrument).
N-Nitrosodiphenylamine reacts in the presence of catalytic amounts of trichloroacetic acid with indoles forming the corresponding nitroso and iso-nitroso derivatives in good yields.
N-Nitrosodiphenylamine can be obtained by reacting nitrous acid with diphenylamine .
N-Nitrosodiphenylamine is a flammable, difficult to ignite, crystalline, green solid that is very slightly soluble in water.
N-Nitrosodiphenylamine is used for heat stabilization of plastics.
N-Nitrosodiphenylamine can be analyzed by this reverse phase (RP) HPLC method with simple conditions.
The mobile phase contains an acetonitrile, water, and phosphoric acid.
For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid.

N-Nitrosodiphenylamine is the N-nitroso analogue of diphenylamine that was once used as a rubber additive but is no longer due to undesirable side effects.
N-Nitrosodiphenylamine is formerly used as a vulcanization retarder in the rubber industry.
N-Nitrosodiphenylamine may be sensitive to moisture at elevated temperatures in strongly acidic solutions.
N-Nitrosodiphenylamine may react vigorously with oxidizing agents.
N-Nitrosodiphenylamine may undergo trans-nitrosation reactions with secondary amines .
N-Nitrosodiphenylamine is probably combustible.
N-Nitrosodiphenylamine is not a naturally occurring substance.
N-Nitrosodiphenylamine is a man-made chemical that is no longer produced in the United States.
N-Nitrosodiphenylamine was used in the manufacture of plastics, resins, rubber and synthetic textiles; to help control processes involved in making rubber products, such as tires and mechanical goods; however, in the early 1980s, the United States manufacturers stopped producing N-nitrosodiphenylamine because new and more efficient chemicals were found to replace its uses.
In addition, the use of N-Nitrosodiphenylamine had several undesirable side effects which do not occur with the replacement chemicals.
