b) Simulation of stress conditions for the accelerated preparation of the searched impurities.
By using stability data or doing own stability tests it is possible to define the circumstances under which the searched compound appears in an accumulated amount. Phytochem® has many years of experience and the required equipment to fulfill the simulation of such complex reaction mechanism.
Chemical as well as physical factors, sometimes even a combination of both, can be decisive for specific manufacturing.

These impurities will be characterized and documented as Primary Standards in the RMF-Format.
Any institutional conditions could be fulfilled by using these reference substances.
In the most cases the preparation is individual for the client. Whereby also the reproduction even some years later can be made quite sure.
