About Ursodeoxycholic Acid-d4

Ursodeoxycholic Acid-d4 (CAS 347841-46-7) is a stable isotope labelled analogue related to Ursodeoxycholic Acid offered by Vaqora Chemicals. Its molecular formula is C24H40O4 and its molecular weight is 396.6 g/mol. It is also known as Ursodeoxycholic-2,2,4,4-D4 acid or Ursodeoxycholic Acid-d4 (Major).

The product is provided as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

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. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

We offer Ursodeoxycholic Acid-d4 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
