About Sulfamethazine-d4

Vaqora Chemicals supplies Sulfamethazine-d4, a stable isotope labelled analogue related to Sulfadimidine registered under CAS number 1020719-82-7. Its molecular formula is C12H14N4O2S and its molecular weight is 282.36 g/mol. The IUPAC name is 4-amino-2,3,5,6-tetradeuterio-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide. It is also known as Sulfamethazine-d4 (benzene-d4).

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. 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. It is used across 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.
