About Zileuton-d4

Vaqora Chemicals supplies Zileuton-d4, a stable isotope labelled analogue related to Zileuton registered under CAS number 1189878-76-9. Formula C11H12N2O2S, molecular weight 240.32 g/mol. The IUPAC name is 1-[1-(1-benzothiophen-2-yl)-1,2,2,2-tetradeuterioethyl]-1-hydroxyurea. Alternative names: Zileuton-d4 (major).

The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the 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. Typical end-use sectors are 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.
