About L-Aspartic Acid-13C4

Vaqora Chemicals supplies L-Aspartic Acid-13C4, a stable isotope labelled analogue related to Aspartic acid registered under CAS number 55443-54-4. Its molecular formula is C4H7NO4 and its molecular weight is 137.07 g/mol. Its systematic (IUPAC) name is (2S)-2-amino(1,2,3,4-13C4)butanedioic acid. It is also known as L-(~13~C_4_)Aspartic acid or L-Aspartic-13C4 Acid.

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. 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. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer L-Aspartic Acid-13C4 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
