Compound libraries are collections of chemical compounds that are stored for research and development purposes. These libraries are essential in fields like drug discovery, where scientists screen various compounds to identify potential new medications. Each compound in a library can have unique properties, making them valuable for testing against specific biological targets. Researchers often use high-throughput screening techniques to evaluate the compounds in these libraries quickly. By analyzing how different compounds interact with biological systems, scientists can discover promising candidates for further study. This process is crucial for advancing knowledge in areas such as pharmacology and biochemistry.
