About N-Nitroso Thiazolidine

Vaqora Chemicals supplies N-Nitroso Thiazolidine, a nitrosamine impurity of Irbesartan registered under CAS number 73870-33-4. The compound has the formula C3H6N2OS, corresponding to a molecular weight of 118.16 g/mol. Its systematic (IUPAC) name is 3-nitroso-1,3-thiazolidine. Common synonyms include N-Nitroso-thiazolidine (Mixture of Isomers) and 3-Nitrosothiazolidine.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. 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 Irbesartan, method validation (AMV) and regulatory filings. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

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