Chemical Structure
Description
The occurrence of S-Methyl-N-(tert-butyldimethylsilyl)-S-phenylsulfoximine is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
S-Methyl-N-(tert-butyldimethylsilyl)-S-phenylsulfoximine (CAS 117893-43-3) is a high-purity analytical reference standard with the molecular formula C13H23NOSSi and a molecular weight of 269.48 g/mol.
Based on its molecular formula C13H23NOSSi, S-Methyl-N-(tert-butyldimethylsilyl)-S-phenylsulfoximine contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 269.48 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.
