About Acetylsalicylic Acid-d3

Acetylsalicylic Acid-d3 is a stable isotope labelled analogue related to Aspirin carrying the CAS registry number 921943-73-9. Formula C9H8O4, molecular weight 183.18 g/mol. The IUPAC name is 2-(2,2,2-trideuterioacetyl)oxybenzoic acid. It is also known as Acetylsalicylic Acid-D3 (Aspirin-D3) or Acetylsalicylic Acid D3 (Aspirin D3).

The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer Acetylsalicylic Acid-d3 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
