Anastrozole EP Impurity C is a pharmacopeial impurity specified in the European Pharmacopoeia for quality control of anastrozole. Chemically known as 2,2′-[5-(Bromomethyl)benzene-1,3-diyl]bis(2-methylpropanenitrile) (C₁₅H₁₇BrN₂), it is used as a reference standard to identify and quantify this specific impurity in anastrozole production and testing.
