About (?)-Naproxen-d3

(?)-Naproxen-d3 (CAS 958293-79-3) is a stable isotope labelled analogue related to Naproxen offered by Vaqora Chemicals. With the molecular formula C14H14O3, it has a molar mass of 233.28 g/mol. Systematically, it is named 2-[6-(trideuteriomethoxy)naphthalen-2-yl]propanoic acid. Alternative names: rac Naproxen-d3 (Methoxy-d3) and ( inverted exclamation markA)-Naproxen-D3.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. 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. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, (?)-Naproxen-d3 is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
