Custom and Toll Synthesis

We have a multitude of technologies at our disposal, allowing us to manufacture tailor-made products from a few grams up to thousands of tons. Our facilities range from laboratory scale to 20 m³ reactors.

There are various ways of co-operation.

AlzChem’s Development Process is highly flexible in order to facilitate an entry into each project phase:

You have an idea, but not the research capability to realize it? We would be happy to co-operate with you on the research. We will take all the time required to discuss your idea with you; we will listen to you and try to understand your requirements, so that an optimal commercial process may be achieved. Trust in one another is for us the basis for successful co-operation.

You may have a simple laboratory synthesis? Upscaling is necessary in order to establish a commercial process and you do not have this capability? Our process optimization methods will analyze your synthesis and identify potential areas of improvement!

Alternatively, you already have a technically sound synthesis procedure, but not the necessary production capacity? With our long-standing experience, we can quickly give you a price indication for a production on any scale. A large range of technologies and modern facilities enable us to carry out a multitude of reaction types as well as multi-step syntheses.

It is our goal to provide product of highest quality combined with an exceptional level of service considering customer specific needs. Needless to add that confidentiality is an integral part of each custom specific Project.

Each phase is accompanied by our in-house support functions:

Technologies

AlzChem has long-standing experience in many fields of organic synthetic chemistry. Numerous procedures are implemented using a broad range of reaction technologies, raw materials and production Equipment:

Core Technologies:

  • Large scale Grignard reactions
  • Gas phase reactions (ammoxidation/ ammonolysis)
  • Synthesis of N-C-N Heterocycles (pyrimidines, triazines, triazoles)
  • Guanylation
  • Dehydrogenation
  • Moisture and oxygen-free conditions
  • Air sensitive / organometallic reactions
  • Multi-step synthesis

Challenging Chemicals:

  • Diethyl Ether
  • Cyanamide
  • Inorganic/ organic acid chlorides
  • Isocyanates
  • Highly "active" compounds

We can commercialize your synthesis quickly and reliably. We are also pleased to determine any safety-relevant technical data for you and we will also deal with any necessary registrations on your behalf.
Pharmaceutical products and their precursors can be produced according to GMP conditions.
