4-Formylantipyrine

Description:

4-Formylantipyrine, also known as 4-formyl-1-phenyl-3-pyrazolone, is an organic compound with the molecular formula C11H10N2O. It is characterized by the presence of a formyl group (-CHO) attached to the 4-position of the antipyrine structure, which is a pyrazolone derivative. This compound typically appears as a yellow to orange crystalline solid and is soluble in organic solvents such as ethanol and acetone, but has limited solubility in water. 4-Formylantipyrine exhibits various chemical properties, including the ability to undergo condensation reactions, making it useful in organic synthesis and as an intermediate in the preparation of other chemical compounds. Additionally, it has been studied for its potential biological activities, including anti-inflammatory and analgesic effects. As with many organic compounds, proper handling and safety precautions are essential due to potential toxicity and reactivity.
