Axon Medchem's selection of building blocks provide chemists world wide with high quality, valuble tools to facilitate the synthesis of there desired compounds. We provide a multitude of aminotetraline-based buibling blocks (e.g. Axon 1028) pimarily used for the synthesis of dopaminergic and/or serotonergic receptor ligands, and a wide variety of other (hetero-)cyclic (e.g. Axon 1284) and/or steroid buidling blocks (e.g. Axon 1170 and Axon 1171) to make interesting and useful research tools. As our valuable Axon Ligands™, building blocks from Axon Medchem are throughly checked by multiple analytical methods (¹H-NMR, HPLC-MS)  to ensure they match up with the high quality standard we demand for synthetic reagents (usually >95% purity by HPLC-MS and free of residual solvents determined by ¹H-NMR).
