The solution WitrynaThe impurity concentration in bulk crystals depends on the initial amount of impurities in the polycrystalline source material (charge). Purification is commonly carried out by recrystallization in an appropriate solvent, selected on the basis of a higher solubility of the impurities as compared to the solubility of the substance to be purified.

Witrynaspreadsheet) of the data is recommended. Impurities should be designated by code number or by an appropriate descriptor, e.g., retention time. If a higher reporting threshold is proposed, it should be fully justified. All impurities at a level greater than (>) the reporting threshold should be summed and reported as total impurities. WitrynaPrior to 2024, the ICH Q3C Guideline Summary Table 2 listed ethylene glycol (EG) as a Class 2 residual solvent with a PDE of 6.2 mg/day.
