intermediates

Intermediates are substances formed during a chemical reaction that serve as temporary steps in transforming starting materials into final products. Think of a reaction as a manufactured process—intermediates are like the intermediate parts or stages that help the raw materials become the finished item. They are essential for understanding how reactions occur and can be targeted to control or optimize the process. Once their role is fulfilled, intermediates usually quickly convert into the final products, making them crucial points in chemical pathways.
