Aprepitant Nitroso Impurity 4 is a nitrosamine-related byproduct formed during the production of the anti-nausea drug aprepitant. Chemically identified as N‑benzyl‑N‑(2‑hydroxyethyl)nitrous amide, it is used as a reference standard in analytical testing and quality control to detect and measure this impurity, ensuring that levels remain within regulatory limits.
