Chemical Structure
Description
CATO supplies 7-Fluorobenzo[c][1,2,5]oxadiazole-4-sulfonyl chloride (CAS 91366-64-2), a certified reference material (molecular formula C6H2ClFN2O3S, MW 236.61 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H2ClFN2O3S, 7-Fluorobenzo[c][1,2,5]oxadiazole-4-sulfonyl chloride contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.61 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.
