Pay-per-Use Browser-Based Predictions

Name chemical structures; predict physicochemical and ADME properties, toxicity endpoints, and NMR spectra.

Browser-based Predictions

I-Lab delivers the advanced algorithms from our desktop software without the need to purchase individual software modules.

  • Effortlessly predict a number of properties including physicochemical, ADME, and toxicity characteristics
  • Expand your knowledge by viewing predicted spectra and chemical shifts for structures
  • Ensure confidence in your structure by generating the IUPAC name

  • IUPAC nomenclature (limited functionality)4

1 Most predictions have a cost of 10 credits per structure-based prediction, while others are free. A paid account is required to access the program.
2 Generate systemic names (IUPAC and names based on CAS rules) for compounds containing up to 255 atoms (excluding H), and structures from chemical names.
3 Included molecular descriptors are available free of charge with a paid account.
4 Generate IUPAC names for molecules with up to 50 non-metal atoms.
