Novel compounds refer to newly discovered chemical compounds that have not been previously described or identified. These compounds often have unique properties or structures that make them of interest to researchers in fields such as chemistry, biochemistry, and pharmacology. The discovery and characterization of novel compounds can lead to advancements in various areas, including drug development, materials science, and environmental remediation. Researchers often use various techniques, such as high-throughput screening, computational modeling, and synthetic chemistry, to identify and study novel compounds.
