In the realm of chemistry, fine chemicals represent intricate, singular, and pure chemical substances. They are crafted in limited quantities within versatile facilities through multi-step batch chemical or biotechnological processes. These chemicals adhere to stringent specifications, find application in subsequent chemical industry processes, and are marketed at a value surpassing $10/kg (refer to the fine chemicals, commodities, and specialties comparison). The fine chemicals category can be further categorized based on added value (building blocks, advanced intermediates, or active ingredients) or business transaction type, distinguishing between standard and exclusive products.
Typically generated in limited volumes (< 1000 tons/year) and at relatively higher prices (> $10/kg), fine chemicals are meticulously produced according to precise specifications. Traditional organic synthesis in multipurpose chemical plants has been the predominant method, although biotechnological processes are progressively gaining prominence. Fine chemicals serve as pivotal starting materials for specialty chemicals, particularly in the realms of pharmaceuticals, biopharmaceuticals, and agrochemicals.
Custom manufacturing for the life science industry is significant, with a notable portion of total production occurring in-house within large user facilities. The industry exhibits diversity, ranging from small privately-owned enterprises to segments within extensive, diversified chemical corporations. The term "fine chemicals" is coined in contrast to "heavy chemicals," which are mass-produced and handled in large quantities, often in an unrefined state.
