Custom Synthesis

Tailor made manufacturing

We manufacture individual, innovative and sophisticated products, applying our kilo lab facilities to seamlessly transfer projects from research to pilot scale and exclusive synthesis at full production scale. This includes performing complex multi-step syntheses.

Kilo lab

We perform small-scale manufacturing of innovative intermediate products ranging from 100g – 10kg, seamlessly transferring the product to pilot scale via our kilo lab.

Initial quantities of expensive intermediates can be delivered flexibly and in less time compared to a pilot plant, shortening the customer’s time-to-market.

Pilot & Scale-up

By providing reliable scale-up from lab development to pilot production, we help achieve ambitious project deadlines. Our team‘s taking care of punctual delivery, based on state-of-the-art chemical and technical expertise, frees up customers‘ resources to be applied elsewhere.

Exclusive synthesis

At two production plants in the industrial park Frankfurt-Höchst, we perform complex, individual multi-step syntheses in more than 80 reactors in various materials ranging from 100 and 5,000 liters, delivering quantities of up to several metric tons.

The flexible design of our assets enables a broad variety of chemical transformations and unit operations, while the close proximity of development, scale-up and commercial manufacturing plants saves time and cost in delivering a project.
