ORGANIC SYNTHESIS - Chiral Building Blocks

Modern synthetic chemistry is almost entirely dependent on asymmetry. Chemists climbing the mountain of a total synthesis, designing a new drug or developing a novel material certainly face the need of an effective introduction of one or multiple stereocenters. This is typically achieved either using asymmetric synthesis or starting from reliable highly optically pure building blocks. We have a full range of enentiomerically pure synthones either with innate chirality (i.e. carbohydrates or amino acid derivatives) or having the stereocenters introduced by asymmetric synthesis. Our chiral building blocks are available in the highest degree of chemical and optical purity, this is achieved by rigorous specifications check from our quality control department. We can supply compounds ranging from few grams to several hundred kgs, should you have any enquire please do not hesitate to ask for a quote.
