Launch of new USP Pharmacopeia product category: API Impurities
The United States Pharmacopeia (USP) has launched a new product range: a list of API impuritiesto facilitate to those responsible for quality control or R&D of medicines or their ingredients to check whether their products are within the predefined parameters.
The API impurities are to be used mainly for the following applications:
Conducting tests in formulation feasibility studies.
Identification or confirmation of peaks, comparing retention times or spectra results
Determination of degradation impurities produced during stress studies or formed during ICH stability testing.
Development, validation and transfer of analytical methods.
These are the API impurities already available for purchase on the CymitQuimica website:
