About N-Nitroso Norfloxacin

Vaqora Chemicals supplies N-Nitroso Norfloxacin, a nitrosamine impurity of Norfloxacin registered under CAS number 74011-53-3. Its molecular formula is C16H17FN4O4 and its molecular weight is 348.33 g/mol. The IUPAC name is 1-ethyl-6-fluoro-7-(4-nitrosopiperazin-1-yl)-4-oxoquinoline-3-carboxylic acid.

The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

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. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

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