3-CPs are primarily used in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs). They serve as key intermediates in the production of compounds that exhibit therapeutic properties, such as anti-inflammatory, anti-cancer, and anti-viral agents. Additionally, 3-CPs are utilized in organic chemistry research to create complex molecules for studying reaction mechanisms and developing new synthetic pathways. Their role in the production of fine chemicals and agrochemicals also highlights their importance in industrial applications.
