WitrynaThe impurity function can be defined in different ways, but the bottom line is that it satisfies three properties. Definition: An impurity function is a function Φ defined on the set of all K -tuples of numbers ( p 1, ⋯, p K) satisfying p j ≥ 0, j = 1, ⋯, K, Σ j p j = 1 with the properties: Φ achieves maximum only for the uniform ...

WitrynaFor an API dose at < 2 g/day, the organic impurities threshold is 0.1%. Any impurity above that threshold need to be identified. Once the structure is known the allowed threshold might increase to 0.5%, alleviating the pressure on the synthesis and purification steps. EPR spectroscopy shines light on otherwise unseen impurities …
