Via RAS

Work backwards from the target structure: identify the bonds you need to form, then pick the RAS Pathway entry whose functional groups, protecting-group pattern, and stereochemistry match. Compare purity, available pack sizes, and stability under your reaction conditions before committing to a route.

RAS Pathway is a top-level listing in our catalogue. Use the filters and search on the listing page to narrow by the attributes that matter for your work, or browse the neighbouring categories from the main navigation.

For RAS Pathway, purity is the headline figure — 95% or better is a common floor for medicinal chemistry, and higher for late-stage steps. Also check isomeric and stereochemical purity, water content for moisture-sensitive groups, storage temperature, and that the pack size matches your scale. All products are supplied for professional research and development use only, and are not for use in humans, animals, diagnostics, or therapy.

Search RAS Pathway by CAS number or SMILES first — close analogs are often listed under a neighbouring subcategory. If nothing matches, custom synthesis and bulk enquiries go to [email protected]. We supply verified businesses, research institutions, universities, and government agencies.
