Frequently Asked Questions

What should I consider when selecting a Drug Discovery product?
Define the transformation first, then narrow the Drug Discovery listing by reactivity, compatibility with your solvent and temperature window, and scale. Where several grades exist, the higher-purity option is usually worth it for downstream steps that are hard to purify.
What does Drug Discovery cover?
Drug Discovery 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.
Which quality data should I check before ordering Drug Discovery?
Review the lot-specific Certificate of Analysis for the Drug Discovery product you have chosen: assay or HPLC purity, identity confirmation by NMR and MS, residual solvents where relevant, and appearance. For reactive or hygroscopic material the storage and handling notes matter as much as the purity figure. All products are supplied for professional research and development use only, and are not for use in humans, animals, diagnostics, or therapy.
Can I search Drug Discovery by structure or CAS number?
Yes. Within Drug Discovery you can search by CAS number, molecular formula, or SMILES to reach exact structures and close analogs, and filter by functional group, purity grade, and pack size. For pricing, bulk quantities, or account eligibility, contact [email protected].
