Interor's main activity is to develop processes for the processing of products under CDA for catalogue products thanks to its multiple technologies.

In order to ensure the optimal reactivity and flexibility essential for the development of complex molecules, industrialization is managed by the chemists in charge of research and development in collaboration with the industrialization teams, until the validation of the processes if necessary.

Based at Calais in the north of France, INTEROR puts at the service of its customers, who are mostly large pharmaceutical and chemical groups, an excellent level of R&D and an industrial site of high technicality that manufactures in the best conditions of compliance with quality standards (approved by the ANSM, the FDA), safety and respect for the environment.
