5-chloropentanal - Introduction
5-chloropentanal (also known as chloropentanal) is an organic compound with the chemical formula C5H9ClO. It is a colorless liquid with a special pungent odor.
5-chloropentanal is mainly used for the synthesis of bioactive molecules and pharmaceutical intermediates. It is an important synthetic raw material and can be used to prepare pesticides, dyes, antibiotics and other compounds. In the field of medicine, it can be used in the synthesis of anti-tumor drugs, antiviral drugs and inducers.
5-chloropentanal can be prepared by a variety of methods. A common method is to react 2-pentanal with chlorine under acidic conditions. Specifically, after 2-pentanal is dissolved in hydrochloric acid, chlorine gas is introduced into the reaction system, and 5-chloropentanal can be obtained after the reaction.
When using 5-chloropentanal, you need to pay attention to its safety. It is a flammable liquid that may explode in case of open fire or high temperature. Contact with skin or eyes can cause irritation and burns, and may cause respiratory and digestive tract irritation. Therefore, when using should wear protective glasses, protective gloves and protective clothing, avoid inhalation of its steam.
