DexLeChem: Services in Chemistry for a Sustainable World

As a high-tech company we offer to develop the reduction or re-using of indispensable, expensive resources in production processes to the pharmaceutical and the flavor & fragrance industry.
In this way we support the "Chemiewende"  which describes the transformation of the chemical industry based on finite fossil resources towards a circular economy.

Our cutting-edge services lead to clear cost advantages in the production of the active ingredients. At the same time more ecological synthetic routes are implemented while maintaining highest product qualities. DexLeChem’s interdisciplinary strategy combines newest methods at the interface of chemistry, physics, and process engineering comprising mathematical, quantum chemical as well as empirical tools. In our own laboratory we are able to test all developed processes very quickly and proof their technical feasibility. Due to our strong reaction engineering background we know how to collect data in a way that they are directly applicable to upscaling purposes. Our development and optimization of chemical and biotechnological processes are thus specifically tailored to an industrial production.

What distinguishes us is our patented know-how, an interdisciplinary approach in R&D as well as our agile project management. Thanks to flat hierarchies we have the flexibility to realize customer’s projects successfully in short term. We provide you with untapped green business opportunities - use the piece in process development that makes the difference!

For further information please contact our Head Business Development Mr. Martin Rahmel or download our company brochure.
