Need a chemistry made to your specification? We find who already makes it — or who can make it — and manage the sourcing from sample through commercial supply.
Custom synthesis is making a chemistry to your specification rather than buying it off a catalog — useful when no standard grade fits, when a molecule is proprietary, or when you need a specific purity, isomer, or impurity profile. RawSource is a sourcing house, not a manufacturer: we find who already makes the chemistry you need, or who can make it to spec, then manage the sourcing from sample and pilot through commercial supply. We do not own a plant. What we bring is the search, the vetting, and the coordination — matching your requirement to a maker with the right technology and capacity, and holding the documentation together.
The cheapest route is usually a chemistry that already exists. Before scoping a custom project, we check whether a standard or comparable grade already meets your spec — if it does, you source it in weeks, not quarters. Custom synthesis is the right answer when nothing off-the-shelf fits: a novel molecule, an unusual purity, a specific isomer, or a controlled impurity profile.
We take your specification — structure or CAS, purity, scale, regulatory market — and match it to a manufacturer that has the process and capacity. You get the technical fit and the sourcing coordination; the making happens at a vetted producer, not on any premises we own. Scale moves in steps, from lab sample to pilot to commercial, so a program is proven before it is committed.
The more precise the specification, the faster the match: the structure or CAS number, target purity and key impurities, the scale you need now and later, the regulatory market, and any timing or IP constraints. A mutual NDA comes first for proprietary chemistry. Your route and your IP remain yours.
We recommend the lowest-cost route that meets your spec, and say so even when that is not a custom project.
| Your situation | The route we source | Typical timeline |
|---|---|---|
| A standard grade already meets your spec | Source the existing chemistry from a vetted producer | Weeks |
| No off-the-shelf grade fits, but the chemistry is known | Place a made-to-spec / toll run with a capable maker | Pilot, then commercial |
| A proprietary or novel molecule | Scope a custom-synthesis project under NDA with a matched producer | Project-dependent |
Custom synthesis makes a chemistry to your specification, often from a defined route; toll (contract) manufacturing runs a defined process at a third-party producer's plant. In practice buyers use the terms interchangeably for "made to my spec by someone else." We source both.
No. RawSource is a sourcing house. We match your requirement to a vetted manufacturer that has the right technology and capacity, and manage the sourcing — we do not operate a plant of our own.
Yes. Custom and toll programs are usually staged — lab sample, then pilot, then commercial — so the fit is proven before volume is committed. Minimums and lead times depend on the chemistry and the producer.
You do. We source and coordinate; we make no claim on the formulations, routes, or intellectual property you develop. A mutual NDA is available before any proprietary chemistry is discussed.
RawSource is a raw-material sourcing house. Guidance here is advisory; candidate materials, grades, and regulatory notes are for reference, and suitability, performance, and regulatory compliance in your finished application remain the buyer's responsibility. Always consult the current Safety Data Sheet (SDS) before handling.
