5-batch analysis 

Central to the product chemistry requirements for registration is the identification, quantification and control of all components present in the substance as manufactured. Our chemists have developed expertise in the separation, identification, synthesis and quantification of impurities that may be present as a very small proportion of structurally similar or isomeric materials. Working closely with our clients, these experts can develop a rational and cost-effective program for identifying and quantifying these impurities within the production batches to obtain successful registration.

Charles River has been conducting regulatory 5-batch analysis programs with many chemical classes for over 20 years, building extensive knowledge of the entire plant protection product and biocide portfolio. Recurrent chemical classes include, but are not limited to:

• Aryloxyalkanoic acids
• Aryloxyphenoxypropionate
• Azoles
• Benzoic acid
• Carbamates
• Chloroacetamides
• Coumarins
• Dinitroanilines
• Neonicotinoids
• Organophosphates
• Oxime carbamates
• Pyrethroids
• Strobilurins
• Sulphonylureas
• 1,3,5-triazines
• Triazoles
• Ureas

Custom synthesis of identified impurities can be arranged.
