Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
n-(4-Aminophenyl)-3,4-difluorobenzene-1-sulfonamide hydrochloride (CAS 1172718-05-6) is a high-purity analytical reference standard with the molecular formula C12H10F2N2O2SHCl and a molecular weight of 320.74 g/mol.
n-(4-Aminophenyl)-3,4-difluorobenzene-1-sulfonamide hydrochloride (C12H10F2N2O2SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
CATO manufactures n-(4-Aminophenyl)-3,4-difluorobenzene-1-sulfonamide hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
