About 1,3-Bis(4-Nitrophenyl) Urea-d8

Listed under CAS 1156508-87-0, 1,3-Bis(4-Nitrophenyl) Urea-d8 is a stable isotope labelled standard available from Vaqora Chemicals. With the molecular formula C13H10N4O5, it has a molar mass of 310.29 g/mol. The IUPAC name is 1,3-bis(2,3,5,6-tetradeuterio-4-nitrophenyl)urea. Alternative names: N,N'-Bis(4-nitrophenyl-2,3,5,6-d4)urea and 4,4'-Dinitrocarbanilide-d8.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

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 1,3-Bis(4-Nitrophenyl) Urea-d8 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
