About Tizanidine-d4

Tizanidine-d4 is a stable isotope labelled analogue related to Tizanidine carrying the CAS registry number 1188331-19-2. Formula C9H8ClN5S, molecular weight 257.74 g/mol. Its systematic (IUPAC) name is 5-chloro-N-(4,4,5,5-tetradeuterio-1H-imidazol-2-yl)-2,1,3-benzothiadiazol-4-amine.

The product is provided 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. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Tizanidine-d4 in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
