4-Pentenoic acid chloride - Introduction
4-pentenoyl chloride(4-pentenoyl chloride) is an organic compound having the form of a colorless liquid. Its chemical formula is C5H7ClO, and in the molecule, the pentenoic acid group is attached to the chlorine atom. It has a pungent odor and is soluble in organic solvents.
4-pentenoyl chloride has certain application value in organic synthesis. It can be used as a starting material for the synthesis of other organic compounds, such as esters, ethers and amides. In addition, it can also be used to prepare other organic compounds, such as anhydrides and fatty acid derivatives.
The preparation of 4-pentenoyl chloride can be completed by reacting pentenoic acid with thionyl chloride. The specific preparation method is as follows: First, pentenoic acid is reacted with thionyl chloride under appropriate temperature and conditions to produce 4-pentenoyl sulfoxide. The 4-pentenoyl sulfoxide is then converted to the 4-pentenoyl chloride by reaction with hydrogen chloride.
Regarding its safety information, 4-pentenoyl chloride is an irritating compound and should avoid skin contact and inhalation. Appropriate handling measures, such as gloves, goggles and protective clothing, are required during use. When stored, it should be kept in a sealed container and away from fire and oxidizing agents.
