About N-Nitroso-Nortriptyline

Listed under CAS 55855-42-0, N-Nitroso-Nortriptyline is a nitrosamine impurity of Nortriptyline available from Vaqora Chemicals. Formula C19H20N2O, molecular weight 292.4 g/mol. Its systematic (IUPAC) name is N-methyl-N-[3-(2-tricyclo[9.4.0.03,8]pentadeca-1(15),3,5,7,11,13-hexaenylidene)propyl]nitrous amide. Common synonyms include N-Nitroso Nortriptyline (Mixture of isomers) and N-nitroso-desmethyl-amitriptyline.

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. It carries the GHS signal word “Warning” with 7 hazard statements. Review the Safety Data Sheet before use.

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 Nortriptyline, method validation (AMV) and regulatory filings. Buyers come mainly from 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.
