About Rhein-13C6

Rhein-13C6 (CAS 1330166-42-1) is a stable isotope labelled analogue related to Diacerein offered by Vaqora Chemicals. Its molecular formula is C15H8O6 and its molecular weight is 290.18 g/mol. Its systematic (IUPAC) name is 4,5-dihydroxy-9,10-dioxoanthracene-2-carboxylic acid. Common synonyms include Rhein-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. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, Rhein-13C6 is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
