4-DIMETHYLAMINOANTIPYRINE(58-15-1) is sensitive to exposure to light. This chemical is readily attacked by mild oxidizing agents in the presence of water. 4-DIMETHYLAMINOANTIPYRINE(58-15-1) is incompatible with acacia, apomorphine, aspirin, chloral hydrate, iodine and tannic acid. | [Air & Water Reactions]
Water soluble. | [Fire Hazard]
Flash point data for this chemical are not available; however, 4-DIMETHYLAMINOANTIPYRINE is probably combustible. | [Chemical Properties]
white crystalline powder | [Application]
Oxidation by Fe(VI) has potential to remove N-nitrosodiumethylamine precursors, including 4-dimethylaminoantipyrine, from drinking water. 4-Dimethylaminoantipyrine is itself an effective scavenger of reactive nitrogen compounds nitric oxide and peroxynitrite, important in the inflammatory response. | [Uses]
Antipyretic; analgesic. | [Uses]
Antipyretic;ACTH secretor | [Definition]
ChEBI: A pyrazolone that is 1,2-dihydro-3H-pyrazol-3-one substituted by a dimethylamino group at position 4, methyl groups at positions 1 and 5 and a phenyl group at position 2. It exhibits analgesic, anti-inflammatory, and antipyretic proper
ies. | [Preparation]
Aminopyrine is synthesized from 4-Aminoantipyrine by catalytic hydrogenation (alkylation). Water is firstly added to the dissolving tank, heated to 50-60°C, put into 4-Aminoantipyrine under stirring, and poured into the hydrogenation tank after complete dissolving. Wash the dissolving tank with water, mix it with the nickel catalyst, and then add it to the hydrogenation tank. The hydrogenation tank was evacuated, then the vacuum valve was closed, hydrogen was introduced, and stirring was started. When the pressure rose to 0.245MPa, the hydrogen was stopped. Add formaldehyde and continue to feed hydrogen. The speed of adding formaldehyde is based on the standard of 1.8-2 cubic meters of hydrogen absorption per 5L of formaldehyde, and the reaction temperature is controlled at 60-85°C. After passing the test, filter by pressure, cool the filtrate to below 25°C, and separate out crystals, which are then filtered to obtain the crude aminopyrine. The crude aminopyrine, ethanol, and activated carbon were heated to 75-80°C, stirred for 1 hour, and filtered under pressure. The filtrate was cooled to 10°C, crystals were precipitated, filtered, washed with ethanol, and air-dried to obtain aminopyrine. | [Brand name]

Aminophenazone, a pyrazolone derivative, has been used as an
antiinflammatory and analgesic agent for over a century. Its use has been
associated with cases of bone marrow depression and agranulocytosis and more
recently it has been claimed to have a carcinogenic potential. Products containing
aminophenazone have been formally withdrawn in many countries and marketing
has been voluntarily suspended in others. Elsewhere, however, proprietary
preparations containing this ingredient may remain available.

Antipyrine was found to be nonmutagenic when screened against Salmonella typhimurium tester strains TA100, TA98, TA97, TA102 and TA104. | [Metabolism]
Aminopyrine is very slowly metabolized by normal neonate. In older infants, a higher amount of exhaled 13-CO2 is observed. In chicken aminopyrine-N-demethylase inhibits the activities of some important P-450 enzymes. It is mostly metabolized through N-demethylation to form monomethyl-4-antipyrine and formaldehyde, which can be measured by colorimetry Nash. Aminopyrine Ndemethylase is almost equal to isoform CYP-3A4 and closely linked to the methylation reaction of drugs.
why Aminopyrine Banned? | [Purification Methods]
It crystallises from pet ether, sublimes between 80o and 90o, and forms metal complexes. [Beilstein 25 H 452, 25 III/IV 3555.] |
