Physicochemical characterization is essential for a fundamental understanding of your API and critical to the drug development process. Every regulatory agency requires a certain level of characterization before any clinical trial can be performed and testing can include pka, LogP/LogD, particle size, surface area, crystallinity, thermal properties, and hygroscopicity. Crystal Pharmatech can look over your development plan and help determine which analyses are appropriate for your API and drug product to maximize the amount of information obtained from routine physicochemical characterization.
