1-(4-Acetylphenyl)piperazine, 1-[4-(Piperazin-1-yl)phenyl]ethan-1-one - Introduction
4-Piperazinoacetophenone(4-Piperazinoacetophenone) is an organic compound with the chemical formula C12H16N2O. It had the appearance of a white crystalline powder.
Nature:
4-Piperazinoacetophenone is a solid substance with a strong odor. It has moderate solubility and is soluble in most organic solvents such as ethanol, ethers and chlorinated hydrocarbons. It is stable at room temperature, but it is easy to burn under the action of high temperature, open flame and strong oxidant. In addition, it is irritating to the eyes and skin.
Use:
4-Piperazinoacetophenone is useful as a pharmaceutical intermediate. It is often used in the pharmaceutical industry to synthesize various drugs, especially antipsychotic drugs such as chlorpromazine. In addition, it can also be used in organic synthesis reactions, such as Bodroux-Chichibabin reactions.
Preparation Method:
The synthesis of 4-Piperazinoacetophenone can be achieved by the reaction of piperazine and phenylacetic acid. First, piperazine is reacted with a basic alcohol or alcohol-water mixture under acidic conditions to produce N-piperazinylacetic acid. Then, N-piperazinylacetic acid and acetophenone were subjected to oxidative condensation reaction to give 4-Piperazino acetophenone.
Safety Information:
When handling and storing 4-Piperazinoacetophenone, take care to avoid inhalation, swallowing, and contact with skin. In case of skin contact, rinse immediately with plenty of water and seek medical help. Keep away from open flames and high temperature sources and store in a dry, well-ventilated place. In addition, the use and handling of the compound must strictly follow the relevant safety procedures.
