About Dimethylnitrosourea

Dimethylnitrosourea (CAS 13256-32-1) is a nitrosamine impurity of Urea offered by Vaqora Chemicals. Its molecular formula is C3H7N3O2 and its molecular weight is 117.11 g/mol. Its systematic (IUPAC) name is 1,3-dimethyl-1-nitrosourea. Alternative names: N,N'-Dimethyl-N'-nitrosourea and N,N'-Dimethyl-N-nitrosourea.

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. Good laboratory practice and suitable PPE are recommended during handling.

It is used as a reference standard for trace-level detection and quantitation of nitrosamine impurities by LC-MS/MS or GC-MS, supporting nitrosamine risk assessments for Urea, method validation (AMV) and regulatory filings. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Dimethylnitrosourea in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
