Non-Exclusive Building Blocks
The non-exclusive building block collection, consisting of about 14,000 products, has been developed to address the limitations of commercially available reagents to enable advanced combinatorial lead generation, hit-to-lead, and lead optimization programs.
The building blocks are available for on-line purchase via Hit2Lead.com. There are no legal restrictions or limitations on acquisition or use of our non-exclusive building blocks. They can be purchased in a broad range of gram amounts from 1 gram to 25 gram. All non-exclusive building blocks are available from stock; most of them are available for RUSH delivery from our San Diego office in pre-packaged 1 gram and 5 gram amounts.
All building blocks undergo extensive quality control by NMR and LC-MS, and purity is guaranteed to be over 95% by both methods.
