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-(4-bromophenyl)-4-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonamide.
N-(4-bromophenyl)-4-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonamide (CAS 338775-38-5), molecular formula C18H11BrClF3N2O3S and molecular weight 507.71 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(4-bromophenyl)-4-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonamide (C18H11BrClF3N2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 507.71 g/mol, it falls into the moderately-high-molecular-weight range. 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-(4-bromophenyl)-4-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)oxy)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.
