Compared with other compounds in its class, the molecular weight of 284.16 g/mol gives 3,4-Dichloro-N-(2-hydroxypropyl)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,4-Dichloro-N-(2-hydroxypropyl)benzenesulfonamide (CAS 1153554-99-4), a certified reference material (molecular formula C9H11Cl2NO3S, MW 284.16 g/mol) for analytical method development and quality control.
3,4-Dichloro-N-(2-hydroxypropyl)benzenesulfonamide (C9H11Cl2NO3S) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3,4-Dichloro-N-(2-hydroxypropyl)benzenesulfonamide 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.
