About L-Methionine-d3

L-Methionine-d3 (CAS 13010-53-2) is a stable isotope labelled analogue related to Methionine offered by Vaqora Chemicals. Formula C5H11NO2S, molecular weight 152.23 g/mol. Its systematic (IUPAC) name is (2S)-2-amino-4-(trideuteriomethylsulfanyl)butanoic acid. Alternative names: L-Methionine (methyl-d3) and L-(~2~H_3_)Methionine.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the 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.

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