Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Bromo-N-(piperidin-3-yl)benzenesulfonamide hydrochloride (CAS 1831244-64-4), molecular formula C11H15BrN2O2SHCl and molecular weight 355.67 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H15BrN2O2SHCl, 4-Bromo-N-(piperidin-3-yl)benzenesulfonamide hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 355.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 4-Bromo-N-(piperidin-3-yl)benzenesulfonamide hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
