Used primarily in pharmaceutical research and development as a key intermediate in the synthesis of various active pharmaceutical ingredients (APIs). It is particularly valuable in the production of compounds with potential therapeutic effects, such as anti-inflammatory, antiviral, or anticancer agents. The ethoxy and chloro functional groups make it a versatile building block for modifying molecular structures to enhance drug efficacy or reduce side effects. Additionally, it finds application in agrochemical research for developing pesticides or herbicides, where its structural properties contribute to the creation of effective crop protection agents.
