Industrial crystallization process development and particle size engineering.

Many of the drug substances and intermediates are isolated as crystalline solids. The solid-state properties have a significant impact on the performance of the final product.

To achieve controlled production of the desired crystalline candidates, Minakem has set up a team of experienced solid-state scientists working closely together to develop reliable and robust industrial crystallization processes.

Our  main missions :

  • Identify and characterise the most suitable candidate crystalline form and morphology
  • Develop a robust and scalable crystallization process: easy to implement from lab to production scale with suitable filtration properties to ensure the required quality attributes of the final product
  • Control the particle size distribution within requested specifications
