Early Development Services

Physical and chemical properties of molecules

Regulatory agencies have requirements your product must comply with. Early testing makes your decisions more informed and saves time. To have the information when you need it (or even before), choose one (or a combination) of our early development services:

1. Preclinical candidate and API characterization

You can rely on us to perform preclinical candidate characterization including the assessment of chemical and physical properties like crystallinity, thermal properties, solubility and stability. These properties can be a limiting factor in the efficacy of the API and can cause unwanted costs. Therefore, we offer screening and characterization of polymorphs, salts and co-crystals, ideally to be performed while a drug candidate is still in the discovery phase.

  • Solubility studies
    • Solubility in organic solvents
    • Solubility in bio-relevant media (SGF, FaSSIF, FeSSIF)
    • Solubility in buffers
    • Solubility in aqueous media with solubility enhancers
  • Stability studies
    • Solution stability
    • Solid state stability
    • Storage conditions according to customer requirements:
      • Open and/or closed vial
      • Various temperatures
      • Various humidity
    • Light stability (ICH conditions)
  • Solid state characterization
    • X-ray powder diffraction (XRPD) – ambient temperature and relative humidity, variable temperature and variable relative humidity
    • Single crystal X-ray diffraction
    • Thermogravimetric analysis (TGA)
    • Differential scanning calorimetry (DSC)
    • Fourier transform infrared spectroscopy (FT-IR)
    • Hot stage and optical microscopy
  • Form and version screening
    • Polymorphs
    • Salts
    • Co-crystals

2. Non-GLP analytical development

You have an analytical method. Or you don’t. Either way, we can help by developing methods tailored to your compound or optimise an existing one. In addition, we can support chemical manufacturing and control activities (CMC) by providing comprehensive analysis of process related substances with impurity profile comparisons. Our offering includes:
  • UPLC / HPLC method development
  • UPLC / HPLC method transfer
 

3. Analytical testing

 

Rules and regulations

  • International Conference on Harmonisation (ICH) guidelines and other globally recognized standards
  • Strict environment, health and safety regulations
  • High data integrity standards to help with your intellectual property protection
  • Scientific reports, Certificate of Analysis and laboratory notebooks are written in English
