Drug Discovery Chemistry
Medicinal chemistry teams lose weeks to compounds nobody sells. WesynTech's catalogue and custom synthesis exist to shorten that wait.
The pressure
What actually goes wrong
A discovery programme is a queue of small decisions waiting on material. A fragment with the wrong substitution pattern, a boronate that no supplier lists, a tool compound quoted at twelve weeks — each one stalls a series.
The answer
Catalogue first
672 compounds are already listed with CAS numbers, so the fastest answer to a request is often that it exists. The catalogue is searchable on this site and downloadable in full.
Custom synthesis when it is not
If the structure is not on a catalogue, it goes to the laboratory instead of back to the requester. Gram-scale is a normal starting quantity.
The awkward classes
Chiral centres, fluorine, boronic acids and esters, and heterocycles are the four areas where WesynTech's technical depth is concentrated — which is where discovery chemistry most often gets stuck.
What this looks like in practice
- Named tool compounds and clinical candidates held under the API heading
- Fragment-sized building blocks with usable handles
- One point of contact from enquiry to delivery
Compounds teams like yours ask for
A sample of what is documented on this site. The searchable catalogue holds 672 compounds in total.
Other teams we supply
Preclinical & Process Development
The jump from milligrams to the first kilo is where routes break. Pilot equipment and the chemists who wrote the route sit in the same building here.
CRO & CDMO Supply Partners
Service organisations are judged on what their own suppliers do. WesynTech works as the upstream chemistry partner behind those programmes.

One structure, one quantity, one date. That is enough for the team to say whether it is a catalogue answer or a custom synthesis project.
