The full path a complex molecule needs — under one roof.
A reason to engage Lewens before a specific product exists: end-to-end process development, analytical science, scale-up and GMP manufacturing, with no hand-offs between disconnected vendors.
From route to commercial supply.
Customers enter at any point — and stay as long as it serves them. Each stage feeds the next without losing process fidelity.
Route scouting
Identifying a viable, scalable and defensible synthetic route.
Process development
Optimising yield, safety, robustness and cost of goods.
Analytical development
Methods, impurity profiling and specification setting.
Scale-up
Moving from lab to kilo to plant scale with control.
Pilot development
Validating the process across pilot batches.
Technology transfer
Transferring cleanly into commercial assets.
Commercial manufacturing
Reliable, compliant, on-specification supply.
Where the depth lives.
Route & process R&D
The hard part of the molecule, solved first — then made robust enough to survive scale.
- Route scouting & selection
- Multi-step organic synthesis
- Hydrogenation
- Impurity control & purge strategy
Analytical development
You cannot control what you cannot measure. Analytical sits alongside chemistry, not after it.
- Analytical method development
- HPLC · GC · wet chemistry
- Impurity profiling
- Specification setting
Pilot, scale-up & commercial
The bridge from bench to plant — where good chemistry either survives or fails.
- Pilot-scale development
- Crystallisation & isolation
- Solvent recovery & recycling
- ~30 reactors · multiple chemistries
Built to carry a process to scale.
~30 reactors
A range of reactor types and volumes to accommodate diverse chemistries and batch sizes.
Process utilities
Heating, cooling, vacuum, solvent handling and recovery to support demanding conditions.
Quality & EHS
GMP quality systems, data integrity and environment, health & safety built into operations.
Note for Lewens: add specific reactor volumes/types, area, capacity and equipment list once confirmed by Engineering.
