Chemical intermediates are substances formed during the steps of a chemical reaction. They are not the final products but play a crucial role in the transformation of reactants into products. These intermediates can be unstable and often require careful handling in laboratory or industrial settings. In many manufacturing processes, such as the production of pharmaceuticals or plastics, chemical intermediates are essential. They help streamline reactions and improve efficiency. Understanding these intermediates allows chemists to optimize reactions and develop new materials, contributing to advancements in fields like medicine and materials science.
