Why Does One Chemical Intermediate End Up in Dozens of Pesticides? Inside the Reaction Interface Economy

A single pyridine intermediate feeds four different neonicotinoid insecticides. A single pyrazole acid feeds a whole family of SDHI fungicides. This isn't coincidence — it's the Reaction Interface Economy, the organizing logic behind modern agrochemical R&D and its supply chain.
