About Methimazole-d3

Methimazole-d3 is a stable isotope labelled analogue related to Methimazole carrying the CAS registry number 1160932-07-9. The compound has the formula C4H6N2S, corresponding to a molecular weight of 117.19 g/mol. The IUPAC name is 3-(trideuteriomethyl)-1H-imidazole-2-thione. Alternative names: Methimazole D3 (Methyl D3) and Methimazole-d3 (methyl-d3).

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. It carries the GHS signal word “Warning” with 3 hazard statements. Review the Safety Data Sheet before use.

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.

We offer Methimazole-d3 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
