Chemical custom synthesis according to your ideas and recipes
Chemical syntheses require extensive expertise and the precise fulfillment of high standards and your specifications. We synthesize customized chemicals for many industries and provide our clients with our equipment and additive know-how.


As a pure contract service provider, our organization is designed for custom synthesis. In other words, we do not manufacture own products, we focus exclusively on developing, manufacturing and refining your chemicals. The ProChem Group has three custom synthesis locations in Dieburg / Hesse, Oberthal / Saarland and Frankfurt to cope with the diverse synthesis orders placed by our customers. All three sites are equipped with custom synthesis equipment. But in addition to technology and suitable processes, our many years of experience is an important success factor for your custom synthesis.
Your advantages when we carry out your order synthesis:
- no investment costs
- no planning and approval costs
- minimization of operational and financial risk
- less staff and administrative work
- fast availability of your products
- improved supply security
- flexibility in optimizing your product
- DIN EN ISO 9001:2015 / 50001:2018 and EFfCI certified
ProChem: Ideal outsourcing partner for custom synthesis
For more than 25 years, we have been a reliable custom synthesis partner for our customers in the chemical and pharmaceutical industries: while we take over your tolling synthesis and formulation of chemical products, you concentrate fully on your core business and also save costs. The custom syntheses we do for our clients are usually very complex and time consuming. They demand daily concentration, flexibility, innovation and sometimes creativity – all the skills that we have and that we are happy to raise for you. We fulfill custom synthesis technically as well as organizationally according to your specifications, recipes and quality standards.
We do the synthesis – our customer save time, money and capacity
Chemical syntheses, especially if they are “only” used to generate intermediates for your actual production, do not have to constrain your capacity. We can carry out custom synthesis efficiently and cost-effectively for your company because we already have the necessary equipment and infrastructure. Coupled with our expertise and our own quality and safety standards, we find a solution for every problem you face.

Custom synthesis for different industries and a multitude of applications
We have modern, modular synthesis plants: Our reactors of 1 to 20,000 liter capacity cover common lot sizes. This is how we have grown to a reliable custom synthesis service provider. At present we are able to optimally handle production sizes from 1 kilo to 5,000 tons. All product-contacting parts of our systems are manufactured either in stainless steel, enamel/glass-lining or Hastelloy/C4 steel. Impurities or cross contamination of your products are minimized. Depending on requirements, the systems are heated with steam, water or thermal oil up to 300°C or cooled down to cryogenic temperatures of -100°C. Cooling towers, cooling units and cooling or thermal insulation systems are available for cooling.
Applications for custom synthesis:
- Organic chemicals for semiconductor production
- Pharma intermediates
- Fine chemicals and cosmetic ingredients
- Primary polymer dispersions

Scale-up and piloting trials
Before we implement your synthesis process in our commercial multi-purpose batch plant, we usually carry out scale-up trials on laboratory scale, adapting your process to our equipment and optimizing the space-time yields. In addition to standard laboratory synthesis, we also have glass reactors (1 liters, 4 liters), a state-of the art kilolab equipment (1 liters, 60 liters) and a several autoclaves for e.g. hydrogenation experiments. Then we can pilot in our pilot plant in 50 liters to 5,000 liters reactor size.
