About Nitroso L-Arginine

Vaqora Chemicals supplies Nitroso L-Arginine, a nitrosamine impurity of Arginine registered under CAS number 2492451-27-9. Formula C6H13N5O3, molecular weight 203.2 g/mol. The IUPAC name is (2S)-5-(diaminomethylideneamino)-2-(2-oxohydrazinyl)pentanoic acid. It is also known as N-Nitroso Arginine.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Handle it with standard laboratory precautions and appropriate personal protective equipment.

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 Arginine, 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.
