DOTTIKON offers small-scale production capabilities to quickly respond to the demand for smaller quantities and scale-up development needs (1 to 50 kg).

DOTTIKON's facilities are suited to the manufacturing of chemical intermediates and active pharmaceutical ingredients (APIs) in clinical trials, as well as for marketed small-volume APIs. The small-scale facilities are equipped to handle high-potency products.

Experience in over 130 different chemical reactions enable DOTTIKON to deliver new complex organic compounds within weeks instead of months.

The stand-alone facility is coordinated by our pilot plant and is operated by qualified staff dedicated specifically to the unit. The two small-scale plants operate according to cGMP guidelines.


A trend towards high-potent and therefore low-dosage drugs is a key challenge for suppliers of intermediates and active pharmaceutical ingredient.

DOTTIKON meets this demand with three stand-alone, fully qualified cGMP pilot/small-scale plants, equipped to handle high-potency products. DOTTIKON has experience in over 130 different chemical reactions and is scaling up over 80 reaction steps per year using its portfolio of core technologies, low-temperature, high-pressure, wet milling, and continuous processing.

DOTTIKON's modular approach to tailor the equipment to specific needs enables these facilities to handle small- to medium-scale production on one hand, and process and technology transfer as well as scale-up to feed our large-scale multipurpose plants on the other hand.


DOTTIKON has nine cGMP multipurpose and specialized multi-ton production plants handling hazardous reactions, high-pressure (50 bar), low-temperature (−100°C), and continuous processing.

As part of DOTTIKON's full volume range manufacturing and scale-up services, versatile large-scale capabilities are offered for the production of up to several 100 tons per product and year, e.g.

  • 300 m3 capacity
  • 9 cGMP multipurpose and specialized multi-ton production plants
  • Dedicated plants for
  • Over 100 different chemical reactions

Quality Control

The quality control unit of DOTTIKON ensures compliance with cGMP guidelines using validated analytical methods on qualified instruments.

As part of DOTTIKON's quality management, the quality control unit is responsible for testing raw materials, intermediates and final products to ensure compliance with specifications. For each material an approved testing procedure is available which defines the different analytical methods, and their acceptance criteria. The tests are carried out according to cGMP standards on qualified instruments that were calibrated in defined intervals. Method validation is performed according to the actual ICH guidelines.

The quality control consists of three laboratory teams for liquid chromatography, GC and non-chromatographic methods including spectroscopic methods as well as pharmacopoeia tests with 40 analysts. Validation of analytical methods is performed in a separate group, Analytical Quality Assurance.
