➢ Limited number of characterisations

− Limited quantities of the compounds are available − Large number of compounds to test in a short period

e.g. chemical libraries in FBLD

➢ Typical studies performed during early development:

Enantiomeric composition

− Partition coefficients at selected pH − Estimated dissociation constant − Solubility at selected pH − Preliminary stability
