Acetylsalicylic Acid-d3 is a deuterated form of acetylsalicylic acid (aspirin), where three hydrogen atoms are replaced with deuterium. This compound is utilized as an internal standard in analytical chemistry, particularly in mass spectrometry, to accurately quantify acetylsalicylic acid in biological and pharmaceutical samples. The deuterium substitution allows for precise differentiation from the non-labeled aspirin, aiding in the analysis of its metabolic pathways and pharmacokinetics. Acetylsalicylic Acid-d3 is valuable in pharmaceutical research for studying drug absorption, metabolism, and excretion, and in clinical settings for monitoring therapeutic levels of aspirin.
