In chemical biology, using compounds with incorrect identity or insufficient purity can lead to misleading biological activity data. Chemical quality control for confirmation of purity and compound identity is thus central to chemogenomics. We have established a medium-throughput LC-MS-based semi-automated quality control (QC) workflow with a minimal requirement for materials suitable for chemogenomics and other small molecule libraries. This rapid method can cover a broad chemical space of small organic compounds with diverse physicochemical properties such as polarity or lipophilicity.
