Roxadustat-d5

About Roxadustat-d5

Roxadustat-d5 is a stable isotope labelled analogue related to Roxadustat carrying the CAS registry number 2043026-13-5. With the molecular formula C19H16N2O5, it has a molar mass of 357.4 g/mol. Its systematic (IUPAC) name is 2-[[4-hydroxy-1-methyl-7-(2,3,4,5,6-pentadeuteriophenoxy)isoquinoline-3-carbonyl]amino]acetic acid.

The product is provided as a powder. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. 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.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
