API solid state property testing

Service Introduction
      Different crystal forms of the same drug have significant differences in stability, manufacturability and bioavailability, which directly affect the efficacy and safety of the drug, therefore, any new drug development requires comprehensive solid-state testing of crystal forms. Accurate and rapid solid-state characterization can not only indicate the direction of drug development, significantly shorten the drug development cycle, reduce the cost and increase the success rate of drug development, but also provide a great help to the subsequent development of the manufacturing process.
Instruments (in part)

Differential Scanning Calorimetry Analyzer, PerkinAlmer DSC8000
Differential scanning calorimetry is a thermal analysis method that measures the difference in power input to the specimen and the participant as a function of temperature at a programmed controlled temperature. It can determine thermodynamic parameters of drug molecules, such as specific heat capacity, heat of reaction, heat of transition, phase diagram, reaction rate, crystallization rate, crystallinity, sample purity, etc.
