About rac Biotin-d4

rac Biotin-d4 is a stable isotope labelled analogue related to Biotin carrying the CAS registry number 1217850-77-5. With the molecular formula C10H16N2O3S, it has a molar mass of 248.34 g/mol. The IUPAC name is 5-[(3aS,4S,6aR)-2-oxo-1,3,3a,4,6,6a-hexahydrothieno[3,4-d]imidazol-4-yl]-3,3,4,4-tetradeuteriopentanoic acid. It is also known as Racemic Biotin-D4 or Vitamin b7 (biotin) (3',3',4',4'-d4).

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. 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.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, rac Biotin-d4 is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
