C40 COMBINATORIAL TECHNOLOGY
Description
C40 covers methods and systems for rapidly synthesizing and screening large numbers of chemical compounds or molecular variants simultaneously. This class encompasses combinatorial chemistry techniques, high-throughput synthesis approaches, and parallel testing methodologies used to discover new materials, pharmaceuticals, agrochemicals, and catalysts. Applications include library generation, automated synthesis platforms, and integrated screening systems that accelerate the identification of compounds with desired properties. The classification excludes general chemical synthesis methods covered elsewhere and focuses on the combinatorial strategy itself rather than the specific chemical reactions employed.
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2006.
