(-)-(1-Oxyl-2,2,5,5-tetramethylpyrrolidin-3-yl)methyl Methanethiosulfonate CAS 681034-15-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 266.40 g/mol gives (-)-(1-Oxyl-2,2,5,5-tetramethylpyrrolidin-3-yl)methyl Methanethiosulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(-)-(1-Oxyl-2,2,5,5-tetramethylpyrrolidin-3-yl)methyl Methanethiosulfonate (CAS 681034-15-1), molecular formula C10H20NO3S2 and molecular weight 266.40 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H20NO3S2, (-)-(1-Oxyl-2,2,5,5-tetramethylpyrrolidin-3-yl)methyl Methanethiosulfonate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 266.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
