The Upstream and Downstream products of (-)-4-(2-Pyrrolidinyl)pyridine

In the chemical industry, the concept of upstream and downstream products is commonly used to refer to the various processes involved in the production of a final product.
Upstream processes refer to the initial stages of production, where raw materials are transformed into intermediate products.
Downstream processes, on the other hand, refer to the final stages of production, where the intermediate products are transformed into the final product.
