Supplier Directory and Selection

Chemspace collaborates with a wide network of trusted reagent manufacturers and suppliers to ensure high-quality materials for research and discovery projects worldwide. Our platform connects customers with verified laboratory reagents suppliers, providing transparent access to stock availability, lead times, and regulatory certificates.
Chemspace runs the largest online catalog of building blocks and screening compounds (over 18 billion of structures). All of compounds are available for searching and purchasing through Chemspace’s online engine with advanced search options.
The catalog of commercially available in-stock building blocks features over 802,000 molecules from worldwide reliable suppliers, like Enamine, BLDpharm, MedChemExpress, and others.
Chemspace offers access to over 1.7 billion virtual make-on-demand building blocks, available for synthesis within 3–4 weeks. These compounds are designed using advanced chemical synthesis strategies and backed by Enamine’s proven track record, ensuring a high synthesis success rate. This enables researchers to explore novel chemical space, design unique libraries, and expand SAR studies with confidence that selected compounds can be delivered reliably.
For projects that require immediate availability, Chemspace provides an in-stock screening collection of more than 7.8 million compounds, ready to be shipped directly from inventory. This “off-the-shelf” access allows discovery teams to kick off high-throughput screening (HTS) campaigns, fragment-based screening, or hit expansion without delays caused by synthesis.
