Chemical Structure
Description
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.
8-Fluoro-1,3,4,5-tetrahydrothiopyrano[4,3-b]indole 2,2-dioxide (CAS 1431081-09-2), molecular formula C11H10FNO2S and molecular weight 239.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H10FNO2S, 8-Fluoro-1,3,4,5-tetrahydrothiopyrano[4,3-b]indole 2,2-dioxide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 239.27 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.
