ArZa Bioscience offers a variety of over 8000 unique isotope labelled products to the Stable Isotope and Nuclear Magnetic Resonance research communities. The variety of products and multiple labelling options available has been designed for maximum flexibility of NMR experiments. If you require a specific isotope labelled compound not listed in this section please contact us for further assistance.

For life science research laboratories we offer a unique and diverse collection of over 400K chemical building blocks which includes heterocyclic (small (hetero) cyclic (fused) ring compounds with one or more chemical handles) such as imidazoles, pyridines, pyrazines etc as well as a variety of alycyclic (piperizines, piperidines, spiro) and substituted aromatic compounds for hit-to-lead, lead optimization, and medicinal chemistry programs.

Most of the compounds are available in multi-gram quantities (1-100g) with a min purity of 95%, making them suitable for high-throughput and combinatorial synthesis or scale-up of lead compounds. Many of the intermediates are offered ex-stock and we typically aim to despatch within 24-48 hours of receiving an order. Where a compound is out of stock we will proactively provide an expected lead-time and delivery date.
