About Nitrosobiotin
Nitrosobiotin is a nitrosamine impurity of Biotin carrying the CAS registry number 56859-26-8. With the molecular formula C10H15N3O4S, it has a molar mass of 273.31 g/mol. Its systematic (IUPAC) name is 5-[(3aR,6S,6aS)-3-nitroso-2-oxo-3a,4,6,6a-tetrahydro-1H-thieno[3,4-d]imidazol-6-yl]pentanoic acid. Common synonyms include 1'-Nitroso Biotin and 1'-Nitrosobiotin.
The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.
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 Biotin, method validation (AMV) and regulatory filings. Typical end-use sectors are 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.
