Profile: Focus Synthesis LLC is a chemical distributor and manufacturer offering small molecule synthons, building blocks & heterocycles with highly distinctive chemical structures. In addition to providing a catalog of rare laboratory chemicals for organic synthesis & drug discovery, we also provide custom synthesis and synthon design services. Our products include members of unique and underrepresented substructure classes, building blocks designed for thorough chemical space coverage, exotic heterocycles & precursors for highly focused combinatorial libraries. We offer synthons, building blocks, and research chemicals that are optimized for drug discovery using cheminformatics-based design. In addition to being a research chemical supplier specializing in drug candidate intermediates and other organic chemicals, we also provide custom synthesis outsourcing, in-house custom chemistry, and proprietary design services. We offer confidential building block design services to help meet the specific requirements for diversity and property space coverage in medicinal & high-throughput chemistry. The synthetic intermediates made through Synthon Design Services℠, known as SDS Building Blocks™, will be substantially distinct from commercially available building blocks.
