4-(Azepane-1-carboxamido)-2-chlorobenzene-1-sulfonyl chloride (CAS 728864-62-8) is a high-purity analytical reference standard with the molecular formula C13H16Cl2N2O3S and a molecular weight of 351.25 g/mol.
4-(Azepane-1-carboxamido)-2-chlorobenzene-1-sulfonyl chloride (C13H16Cl2N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
