Solid state characterization
The need to investigate the solid-state properties of Active Pharmaceutical Ingredient (API) has become important in the pharmaceutical development industry. Physical properties can vary widely between batches, leading to batch to batch variability. Sometimes this can be attributed to difference in crystalline forms or mixtures of amorphous and crystalline.
Our highly skilled scientists can undertake studies that range from routine to highly complex and challenging characterization. We can perform physical and chemical characterization of Active Pharmaceutical Ingredient (API) and Drug Product during all phases of the drug development process. A clear and concise report will be provided summarizing all findings and can be QA reviewed for GMP projects.
