All our fine chemicals are produced in our own plant in The Netherlands under current Good Manufacturing Practice (cGMP) guidelines. The major volume of our fine chemicals is used as advanced intermediate in the production of Active Pharmaceutical Ingredients (APIs) or as excipient. A range of small volume fine chemicals is used in a variety of industrial applications. For example, we can offer a wide range of substituted Pyrimidines, Pyridines and Pyrazoles. We also toll manufacture fine chemicals on an exclusive and confidential basis.

Katwijk Chemie generally has several new products in active development.
In close cooperation with customers we evaluate feasibility and manage projects step-by-step. For process development we often involve partner companies, such as Contract Research Organisations (CROs), for specialized needs.
Our main strength is in products with volumes between 100 kg and 100 MT per year with up to 5 synthetic steps. We have experience in many types of processes, such as large scale cyanation and vacuum distillation. We look forward to reviewing any requirements that you may have.
