Pharmaceutical Impurities
These are highly purified substances that are provided specifically for use in the official test methods of the different pharmacopeia monographs. When used as part of the relevant official monograph they provide the means to verify the compliance of a material with the monograph's standards for identity, concentration, quality and purity.
These fulfill regulatory requirements for universal qualitative and quantitative pharmaceutical quality control.
