APIs and specialty chemicals, including the ones nobody stocks.
An index of 54,748 products to start from, and a sourcing desk for everything outside it.
Nine kinds of material, one enquiry process.
Active pharmaceutical ingredients
20,006 APIs indexed, from high-volume generics to recently approved oncology actives.
Intermediates and KSMs
4,164 advanced intermediates, key starting materials and impurity references.
Catalysts and reagents
Palladium and platinum catalysts, organocatalysts, coupling reagents and protecting groups.
High-purity solvents
HPLC, GC and pharma-grade solvents, anhydrous and deuterated grades.
Peptides and amino acids
Protected amino acids, peptide APIs, linkers and custom peptide synthesis.
Reference standards
Pharmacopoeial standards, impurity standards and nitrosamine references.
Chiral building blocks
Enantiopure amines, alcohols, amino alcohols and heterocycles for route development.
Custom synthesis
Milligram reference quantities through to multi-kilogram campaigns with full analytical packages.
Oncology actives for focused sourcing.
Kinase inhibitors, cytotoxics and newer targeted agents where qualified sources are scarce. Each links to its catalogue record.
Specify it once. We hold every offer to it.
Tell us the grade and the documents your QA team needs. Offers that cannot meet them are dropped before they reach you.

Need a molecule nobody lists?
Send a name, CAS number, SMILES or drawing. We match it with custom-synthesis partners for milligram reference quantities through to multi-kilogram supply, with the analytical package agreed up front.
- IdentityName, CAS number, SMILES or a structure drawing
- SpecificationPurity, assay, impurity limits and grade
- ScaleQuantity per order and expected annual volume
- AnalyticsHPLC, NMR, MS, residual solvents or chiral purity

Tell us what you need.
Send the molecule and the quantity. We reply with what we can confirm, what we still need from you, and a realistic lead time.
