Better-informed decisions in early drug development

Early identification of the best candidates to advance to preclinical and clinical trials has a significant impact on the chance for success in drug development. It reduces the risk of costly late-stage failure, improves the safety of clinical trials and boosts the chances of successful market entry.

Reaxys supports chemists involved in pharmaceutical R&D with relevant literature, accurate and comparable physicochemical and bioactivity data points, and tools to ensure that the data are easily incorporated into in silico modeling workflows.

In addition, Reaxys helps chemists determine the optimal means to synthesize a drug-like compound, including information about sources for reagents, catalysts and starting materials.
