About N-Nitrosourea

N-Nitrosourea (CAS 13010-20-3) is a nitrosamine impurity of Fluorouracil offered by Vaqora Chemicals. With the molecular formula CH3N3O2, it has a molar mass of 89.05 g/mol. The IUPAC name is nitrosourea. Common synonyms include Urea, nitroso- and Urea, N-nitroso-.

The product is provided as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

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 Fluorouracil, method validation (AMV) and regulatory filings. It is used across pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, N-Nitrosourea is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
