NAPQI (Standaard)

NAPQI (Standard) is the analytical standard of NAPQI. This product is intended for research and analytical applications. NAPQI is the toxic metabolite of Acetaminophen (HY-66005). NAPQI is also an inhibitor of enzymes in the vitamin K cycle. NAPQI is rapidly detoxified by glutathione (GSH), but in situations of GSH deficiency, excess NAPQI reacts with cysteine residues in proteins, causing cell death and toxicity in the liver[1][2].
