        Custom synthesis at AlzChem - many years of experience and diverse technologies

        Toll manufacturing

        In our multi-purpose plants at the Trostberg site, a multitude of technologies for custom syntheses are at your disposal. Besides cyanamide and heterocycle chemistry, our expertise includes Grignard syntheses and gas phase reactions. As part of our custom manufacturing activities, we operate equipment for the safe handling of highly air- and moisture-sensitive organometallic products. In addition to Grignard reactions, the current portfolio includes the handling of silicon, lithium, aluminum and titanium compounds.

        Flexibility and speed with high implementation rates for new projects are important competencies of AlzChem. By establishing a cross-functional organization we have exactly the right people in a team to work on projects efficiently and implement decisions quickly. Successful growth with our customers confirms our modern way of teamwork.

        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:

        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:

        As a supplier of raw materials for the pharmaceutical industry, AlzChem is now also helping to produce “corona tests”: intermediate products from AlzChem are used in both tests that detect SARS-CoV-2 and the tests used to detect antibodies.   For many years AlzChem has been reliably supplying various pharmaceutical companies with the two intermediate products guanidine hydrochloride and guanidine thiocyanate. Both are now also used to manufacture the corona tests that are currently...

        From the group of organosilicon compounds, triethylsilane is used as a reducing agent and for hydrosilylation. The high product purity of triethylsilane is crucial for the pharmaceutical industry, especially for new developments of highly effective antivirals. An antiviral drug inhibits the multiplication of viruses and therefore is used as a drug in the treatment of infectious diseases caused by viruses. REACH registered, triethylsilane has been produced in large volumes for over 10...
