Apart from selling the samples of unique organic substances, we offer the synthesis of building blocks for "combinatorial chemistry" in amount of up to 100-200 g. You can find some promising structures in our database of building blocks synthesized to order. About 1720 chemical building blocks are available in stock and can be ordered on-line via our store. These compounds are available in multi-gram (1-100 g) quantities (purity =>95%) which make them suitable for high throughput and combinatorial synthesis or scale-up of lead compounds.
