About N-Nitroso Cytisine

Vaqora Chemicals supplies N-Nitroso Cytisine, a nitrosamine impurity of Cytisine registered under CAS number 19634-60-7. The compound has the formula C11H13N3O2, corresponding to a molecular weight of 219.24 g/mol. The IUPAC name is (1R,9R)-11-nitroso-7,11-diazatricyclo[7.3.1.02,7]trideca-2,4-dien-6-one. Common synonyms include N-Nitroso cytisine (Mixture of isomers).

It is supplied 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.

Laboratories use this nitrosamine standard to develop and validate highly sensitive LC-MS/MS methods, to confirm limits of detection and to document nitrosamine risk assessments in regulatory submissions. Our customers for this product work in 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.
