Product Libraries

The supply base behind every program

Small-molecule and biologics libraries in one place — APIs, intermediates, excipients, custom synthesis, nucleic acids, peptides, antibodies and bioprocessing support.

Supply foundation

The manufacturing base behind every program

These libraries show the currently listed portfolio. They are not a catalogue to browse in isolation — they are the supply base that FSO and FSO+ programs draw on, and anything not listed can be sourced or synthesised to specification.

What determines whether a supply arrangement holds is not whether a molecule appears on a list. It is qualification depth, documentation discipline and continuity planning.

Beyond the list

A listed molecule is the start, not the deliverable

Finding a producer is rarely the hard part. Keeping the arrangement intact through audits, documentation updates, regulatory change and site disruption is.

Supply program

Qualified, documented, continuous supply

Producer identification and qualification, specification alignment, documentation packages and ongoing performance review — run as a program rather than a series of purchase orders.

API & intermediate supply

Single accountability

One party answerable for the whole chain

Sourcing, auditing, regulatory documentation, process support and logistics coordinated by one responsible entity instead of five you manage separately.

How FSO works

Continuity

Knowing where the chain is thin

Upstream concentration mapping, qualified alternatives held ready, and mitigation sized to what an interruption would actually cost you.

Risk management

Looking for something not listed?

Send the molecule, the specification and the market you are filing in. We will tell you whether we can supply it, what qualification would involve and how long it takes.
