Acetylsalicylic Acid-d4 is a deuterated form of acetylsalicylic acid that is used in analytical chemistry for quantification and method development. The incorporation of four deuterium atoms makes it an ideal internal standard for mass spectrometry, as it closely mirrors the physical and chemical properties of acetylsalicylic acid while being distinguishable based on its mass difference. In studies of metabolic pathways, Acetylsalicylic Acid-d4 helps researchers track the compound′s biotransformation and to understand its interaction with biological systems. It is also used in environmental analysis to monitor the presence of acetylsalicylic acid in various samples, such as water sources, to assess its environmental impact.
