Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(3-(3,6-dibromo-9H-carbazol-9-yl)-2-hydroxypropyl)benzenesulfonamide.
N-(3-(3,6-dibromo-9H-carbazol-9-yl)-2-hydroxypropyl)benzenesulfonamide (CAS 331972-29-3) is a high-purity analytical reference standard with the molecular formula C21H18Br2N2O3S and a molecular weight of 538.25 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, N-(3-(3,6-dibromo-9H-carbazol-9-yl)-2-hydroxypropyl)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 538.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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 N-(3-(3,6-dibromo-9H-carbazol-9-yl)-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.
