(R)-1-(3,5-Dichlorophenyl)ethanamine is primarily used in the pharmaceutical industry as a chiral intermediate in the synthesis of various active pharmaceutical ingredients (APIs). Its enantiomeric purity makes it valuable for producing drugs with specific stereochemical requirements, particularly in the development of central nervous system (CNS) medications and antidepressants. Additionally, it serves as a building block in organic synthesis for creating compounds with potential biological activity, such as antimicrobial or antifungal agents. Its application is also explored in agrochemical research for developing pesticides or herbicides with improved efficacy.
