Reaxys for Pharmaceutical R&D

Pharmaceutical companies need to develop preclinical candidates early, efficiently and safely. When this process is successful, they make better informed go/no-go decisions. And significantly reduce time to market and R&D costs. Chemists at pharmaceutical companies, biotechnology companies and CROs choose Reaxys to enhance workflows during:

  • Hit identification

  • Lead generation/Hit-to-lead (H2L)

  • Lead optimization

  • Preclinical candidate selection

Medicinal, synthetic and computational chemists, pharmacologists and information professionals use Reaxys to:

  • Find normalised ADMET and SAR, physicochemical properties and reaction data

  • Filter on specific terms and substructure to rapidly assess large hit sets of bioactivity data

  • Identify the most efficient and economical routes to synthesize compounds

  • Integrate in-house content from ELNs and inventory systems to create a single chemistry portal

  • Stay up to date with the competitive landscape and assess the novelty of compounds

"The Reaxys synthesis plans have links to commercial availability databases, including eMolecules. That’s important for us — we always need reliable availability information."

Reaxys for Chemical R&D

Chemical companies choose Reaxys to get from concept to market successfully with minimum financial risk. Reaxys helps chemists at critical stages in their chemical projects:

  • Projects evaluation

  • Experimental procedure design

  • Scale-up

  • Process improvement

Reaxys connect chemists in chemical R&D directly with relevant information to:

  • Optimize synthesis routes

  • Manage yield expectations and by-products

  • Identify desirable chemical properties in intermediate and end products

  • Find up-to-date commercial availability of substances with detailed purchasing information

  • Get a cross-disciplinary view of chemical substance properties and reactions

Reaxys data can also be integrated into existing informatics workflows to facilitate analytics, modeling and sharing.

See how Reaxys can help you overcome challenges and lead to breakthroughs in chemical R&D.

"I’m impressed with the linking from Reaxys to sources, especially to patent content because navigating the different patent systems can be very time-consuming."
