Custom synthesis

Complex chemistry, delivered with precision.

Custom synthesis of every molecule in our research catalogue — and solutions for novel molecules that have never been made. A scoped project with a defined deliverable, a specification agreed up front, and characterisation data that stands up to review.

Capabilities

Scoped like a project, not a purchase order.

Impurities, degradants and metabolites

Synthesis and isolation of API impurities, degradation products and metabolites — including nitrosamine impurities and stable isotope labelled standards — for steroids, hormones, antibiotics, antifungals, oncology and antiemetic APIs.

Milligram to multi-kilogram

Complex organic molecules, multi-step synthesis, novel building blocks and advanced intermediates at the scale your programme needs.

Route scouting & scale-up

Route scouting, process optimisation and scalable synthetic pathway development.

Complete characterisation

Structure confirmed by NMR and LC-MS, HPLC purity reports and a Certificate of Analysis with every delivery.

IP protected, FTE or FFS

Uncompromised confidentiality and strict IP protocols, with full-time-equivalent or fee-for-service engagement shaped around your timelines and deliverables.

How it works

Four steps from brief to delivery.

  1. Share the brief

    The structure or a description, plus the quantity if you know it — links and files welcome.

  2. Feasibility review

    Synthesis R&D assesses routes, flags hazardous steps and confirms what is realistic.

  3. Written proposal

    Scope, deliverable specification, indicative timeline and documentation included.

  4. Synthesis & delivery

    Progress updates at agreed milestones, then characterised material with its data pack.

Project inquiry

Tell us what you need made.

Share as much as you are comfortable sharing at this stage. A confirmed structure is not required to start — a proposed structure, an accurate mass, or even a retention time and the parent API is enough for a first feasibility view.

  • Reviewed by synthesis R&D, not a sales inbox
  • Feasibility assessed before any commitment is made
  • NDA in place before technical detail is exchanged
