Witryna23 cze 2008 · potency often means the amount of the desired compound in the sample: when you weigh 100 mg of a standard with 90% pontency, there's only 90 mg of the targeted compound in there. in most cases, purity = chemical purity. that is, percentage of the target compound as determined by the primary method. if HPLC with UV detection …
WitrynaExposure (PDE) as described in Appendix 3 of ICH Q3C (R4) “Impurities: Guideline for Residual Solvents” and Appendix 3 of VICH GL 18 on “residual solvents in new veterinary medicinal products, active substances and excipients (Revision)” . The PDE represents a substance-specific dose that is Witryna129 below 1%. Consequently, exposure to these impurities will be low. Therefore, the focus of a safety 130 evaluation of any new impurity or impurity with an increased specified level would be to identify 131 impurities with toxic properties, even at these low levels of exposures. Ultimately, the goal is to
Witryna19 lis 2024 · Impurity formation needs to be understood and then controlled during development and follow-on scales. Identification of impurity formation early in development can avoid complications at later – and more costly stages.
