Fine chemicals: as the commodity chemicals, they are chemical substances characterized by their chemical structure, but, on the contrary of commodity chemicals, they are produced in a small quantity; fine chemicals can be used as components in the formulation of speciality chemicals; [2] for example active ingredients of pharmaceutical drugs ...
In terms of molecular structure, one distinguishes first between low-molecular-weight (LMW) and high-molecular-weight (HMW) products. The generally accepted threshold between LMW and HMW is a molecular weight of about 700 g/mol. LMW fine chemicals, also designated as small molecules, are produced by traditional chemical synthesis, by microorganisms (fermentation or biotransformation), or by ...
