About Apremilast-d5

Apremilast-d5 (CAS 1258597-47-5) is a stable isotope labelled analogue related to Apremilast offered by Vaqora Chemicals. With the molecular formula C22H24N2O7S, it has a molar mass of 465.5 g/mol. It is also known as (S)-Apremilast D5 or Apremilast D5 (racemic).

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. Handle it with standard laboratory precautions and appropriate personal protective equipment.

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. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
