About Alpha Lipoic acid-d5

Vaqora Chemicals supplies Alpha Lipoic acid-d5, a stable isotope labelled analogue related to Lipoic acid registered under CAS number 1189471-66-6. Formula C8H14O2S2, molecular weight 211.4 g/mol. Systematically, it is named 5,5-dideuterio-5-(3,4,4-trideuteriodithiolan-3-yl)pentanoic acid. Alternative names: rac α-Lipoic Acid-d5 and rac- alpha-Lipoic Acid-D5.

It is supplied 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.

We offer Alpha Lipoic acid-d5 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
