Fountainbridge are experts in the custom synthesis and manufacture of small organic molecules. Our custom synthesis and custom manufacturing activities are conducted at specialist facilities where we produce high quality organic molecules synthesised on scales from mg to hundreds of kg.


Fountainbridge specialise in the synthesis of

Fountainbridge has strengths in custom synthesis for drug discovery & development; as well as expertise in process development, optimisation and scale-up. Our dedicated team of chemists operate in facilities including 32 fume cupboards, kilo-scale labs, 12 reactors from 50-500L and 100-500L autoclaves.

All our products are supplied with a detailed certificate of analysis including NMR, HPLC and MS to confirm identity and quantify purity. On request, additional analytical techniques and methods can be utilised to analyse a custom synthesised compound, these include solvent residue analysis (headspace GC), 2D NMR, water content (Karl-Fisher), trace metal levels and X-ray crystallograph.

Fountainbridge offers a bespoke custom synthesis service tailored to our customer’s needs. Before starting a project we will discuss with the customer their specific quantity, product specification, analysis and lead time requirements. Once a custom synthesis project is underway, we will provide regular updates on our progress and we are always available to discuss projects with our customer, if required.

Fountainbridge’s experienced and highly-skilled team of chemists are focused on providing cutting-edge chemistry combined with excellent customer service to ensure you receive a high quality custom synthesised product that will meet the demands of your research and development.
