4-(2,4-Dichlorophenoxy)butanoic acid(CAS: 94-82-6)

4-(2,4-Dichlorophenoxy)butanoic acid is a white to off-white crystalline solid. Its molecular weight is approximately 289.03 g/mol. It is slightly soluble in water and highly soluble in organic solvents. The compound is reactive towards bases and can undergo hydrolysis under basic conditions. It is not flammable but is corrosive and can irritate skin and eyes.

4-(2,4-Dichlorophenoxy)butanoic acid is typically synthesized via the reaction of 2,4-dichlorophenol with acetic anhydride followed by hydrolysis. The synthesis involves the condensation of 2,4-dichlorophenol with acetic anhydride, yielding 2,4-dichlorophenylacetic acid, which is then hydrolyzed to give the final product. Commonly, the reaction is performed in the presence of a catalyst such as sulfuric acid or p-toluenesulfonic acid, with high yields and good selectivity.

4-(2,4-Dichlorophenoxy)butanoic acid is primarily used in the pharmaceutical industry as an intermediate in the synthesis of certain drugs. It is also used in the agricultural sector as a component in herbicides. Additionally, it finds applications in the polymer industry, where it can be used as a stabilizer or additive, as well as in the development of sensors and other specialized chemical products.

Proper personal protective equipment (PPE) should be worn when handling 4-(2,4-Dichlorophenoxy)butanoic acid, including gloves, goggles, and a laboratory coat. It should be stored in a cool, dry place away from heat and direct sunlight. Spills should be handled with caution using appropriate absorbent materials, and the area should be well-ventilated. It is important to have a safety data sheet (SDS) readily available for reference and to follow all laboratory safety protocols.
