About 1,2-Phenylenediamine-d4

Vaqora Chemicals supplies 1,2-Phenylenediamine-d4, a stable isotope labelled standard registered under CAS number 291765-93-0. With the molecular formula C6H8N2, it has a molar mass of 112.17 g/mol. Systematically, it is named 3,4,5,6-tetradeuteriobenzene-1,2-diamine. Alternative names: benzene-d4-1,2-diamine and 1,2-Benzenediamine-3,4,5,6-d4.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. 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. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer 1,2-Phenylenediamine-d4 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
