N-Nitroso Tryptophol

About N-Nitroso Tryptophol

N-Nitroso Tryptophol is a nitrosamine impurity of Tryptophol carrying the CAS registry number 120314-14-9. Formula C10H10N2O2, molecular weight 190.2 g/mol. Its systematic (IUPAC) name is 2-(1-nitrosoindol-3-yl)ethanol. Alternative names: 2-(1-nitroso-1H-indol-3-yl)ethanol and 1-Nitrosotryptophol.

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. 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 Tryptophol, method validation (AMV) and regulatory filings. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

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