Comprehensive Analytical Services to Support Development and Manufacturing

The analytical team at Asymchem provides comprehensive analytical supports to R&D activities, process development, production, and testing services for both drug substances and drug products. Our experts have a full spectrum of know-how knowledge and experiences with small molecules, biological molecules, peptides, oligonucleotides, ADCs and many other chemical modalities. Dedicated analytical R&D and quality control teams conduct phase-appropriate method development, validation, verification and transfer to support projects through their life-cycles from pre-clinical to commercialization. In addition, we can provide in-house stability studies, structural elucidation, impurity preparation and characterization, physicochemical property characterization, cleaning validation, process analytical technology (PAT) and more. Up to now, hundreds of different projects with a wide range of chemical modalities at various clinical and commercial stages have been successfully analyzed, developed and delivered at Asymchem.
