About N-Nitroso Leucine Impurity

Vaqora Chemicals supplies N-Nitroso Leucine Impurity, a nitrosamine impurity of Leucine registered under CAS number 78814-91-2. Formula C8H14N2O4, molecular weight 202.21 g/mol. The IUPAC name is (2S)-2-[acetyl(nitroso)amino]-4-methylpentanoic acid. It is also known as N-Acetyl-N-nitroso-L-leucine or N-Nitroso Leucine Impurity 1.

The product is provided 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 Leucine, method validation (AMV) and regulatory filings. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

We offer N-Nitroso Leucine Impurity in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
