Engagement

How a project actually runs.

No black boxes. You see the route before we commit, and the data as it is generated.

  1. 01

    Enquiry & scoping

    Send the compound name, CAS number or the chromatogram you are trying to explain. We confirm availability, scale and lead time — usually within one working day.

  2. 02

    Route & feasibility

    For non-catalogue compounds our chemists propose a synthetic route, flag the risks and agree a milestone plan before work begins.

  3. 03

    Synthesis & purification

    Synthesis, work-up and purification to the agreed purity specification, with in-process checks at each stage.

  4. 04

    Characterisation

    Identity and purity established by NMR, mass spectrometry, chromatography and IR, and the analytical dossier compiled.

  5. 05

    Release & dispatch

    Batch released against the characterisation protocol, packed under inert conditions where required, and shipped with full documentation.

Start here

What we need from you.

The more of this you can send, the faster and more accurate our first answer will be — but a compound name on its own is a perfectly good place to start.

  • 1

    Structure or name

    A structure, a CAS number, a pharmacopoeial impurity designation — any one is enough to begin.

  • 2

    Analytical data

    Retention time, UV spectrum, mass and the method conditions, if you have an unknown peak.

  • 3

    Quantity and purity

    How much you need, and the purity your method requires.

  • 4

    Timeline

    When you need it in hand, and what it is blocking.
