L-Alanine-d4

About L-Alanine-d4

L-Alanine-d4 is a stable isotope labelled analogue related to Alanine carrying the CAS registry number 18806-29-6. Formula C3H7NO2, molecular weight 93.12 g/mol. Its systematic (IUPAC) name is (2S)-2-amino-2,3,3,3-tetradeuteriopropanoic acid. Alternative names: L-Alanine-2,3,3,3-d4 and TMID-0877.

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. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

We offer L-Alanine-d4 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
