Research intermediates · 1 g to 100 g
Grams,
not kilograms.
Manufacturers sell intermediates by the kilo. Your reaction needs five grams. We hold the stock, split it, document every lot and ship it — so the research doesn’t stop while you wait.
1 g → 100 g
Packs sized for the bench
Split from kilogram lots into the amount a project needs. No minimum order.
CoA · SDS
Documents with every lot
Lot certificate of analysis and safety data sheet in English, before you order and in the box.
Verified
Institutions only
We sell to research institutions and companies we have checked — that is why labs can trust the chain.
Worldwide
Export by express courier
Classified, packed and documented for air transport to labs outside Korea.

Why we exist
Waiting for a reagent is research time that disappears.
Without someone in the middle who splits kilos into grams, a lab either makes the intermediate itself or waits months — and sometimes changes the project instead.
Aldrich began in 1951 because chemists couldn’t buy what they needed. Enamine’s gram-scale stock changed how fast drug discovery moves. We’re building the same thing for the intermediates the big catalogues leave on back-order: stock on the shelf, real documents, and only as much as you need.
About gramsource →Customer verification
We check who we sell to.
That’s the point.
Most intermediates have more than one use. We don’t drop useful compounds from the catalogue — we verify the buyer, with checks scaled to each compound.
How verification works →Institution, contact and intended use confirmed with the order.
Institutional verification and a signed end-use statement on every order.
Only under the licences and notifications the law requires.
