About Quinidine-d3

Quinidine-d3 (CAS 1267657-68-0) is a stable isotope labelled analogue related to Quinidine offered by Vaqora Chemicals. The compound has the formula C20H24N2O2, corresponding to a molecular weight of 327.4 g/mol. Systematically, it is named (S)-[(2R,4S,5R)-5-ethenyl-1-azabicyclo[2.2.2]octan-2-yl]-[6-(trideuteriomethoxy)quinolin-4-yl]methanol. Common synonyms include TMIH-0469.

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. Good laboratory practice and suitable PPE are recommended during handling.

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.

Vaqora Chemicals supplies Quinidine-d3 in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
