Take your search offline. With integrated access to our detailed databases.

For larger orders, work with data securely on a larger scale and integrate it flexibly into your workflow. Create internal library selections, filter by price, availability, lead times and more,

Direct Database access via FTP or API

If you prefer to search offline or need deeper, more granular data on compound sets, you can download or access our databases directly. Options including filtering, diversity analysis, clustering and virtual screening and docking will help simplify and enhance compound selection.

Specialist Searches

Focus you search on natural compounds

Our dedicated natural compound database collects the most reliable natural product suppliers. Featuring over 10,000 unique natural products and 100,000 natural-like compounds - accessible by FTP.

Natural compounds

Speed up your search with pre-plated libraries

To make your search more effective and research time shorter, use our specially-priced database of pre-calculated libraries.

Pre-plated libraries
Cluster Search

Make complex search sets manageable with cluster search

Similarity searching, clustering, and filtering can all help explore chemical space and reduce an overwhelmingly large set of potential structures to a more manageable subset of representative compounds that might be synthesised or acquired. These 'clusters' can be searched with our other tools to see what is available and affordable and deliverable in the right time scale.

Molport compound subsets

Cluster search case study

Universities of Liverpool and Manchester in the UK, Denmark Technical University

The Challenge

Create and acquire a reduced, diverse subset of representative compounds that covered a substantial part of the natural product chemical space. By clustering products into smaller subset groups using Molport's tools, see more easily what was commercially available at that time and good value – and matching that up with fixed timing requirements.

The Result
117 compounds identified from 15 suppliers
134 compounds ordered
133 compounds delivered within the 4-week deadline
