Aminopyrine (4-dimethylaminoantipyrine) is an antipyretic and analgesic chemical intermediate primarily synthesized via the condensation of 2,4-dimethyl-3-nitrosopyrazole with dimethylaniline. Its molecular formula is C13H16N4O with CAS No. 57-50-5. Historically significant in pharmaceutical manufacturing, it serves as a key precursor for various drug formulations.
Aminopyrine is restricted or banned for human therapeutic use due to severe agranulocytosis risks. Handling requires strict PPE including respirators and chemical-resistant gloves. Store in a cool, dry, well-ventilated area away from oxidizers and moisture.
