Chemical Structure
Description
Methyl 3-(4-((3-fluorophenyl)sulfonamido)phenoxy)thiophene-2-carboxylate (CAS 900015-22-7) is a high-purity analytical reference standard with the molecular formula C18H14FNO5S2 and a molecular weight of 407.44 g/mol.
Based on its molecular formula C18H14FNO5S2, Methyl 3-(4-((3-fluorophenyl)sulfonamido)phenoxy)thiophene-2-carboxylate contains a flavonoid core, 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 407.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
