Chemical Structure
Description
The occurrence of 5-Chloro-2-((tetrahydrofuran-3-yl)methoxy)benzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Chloro-2-((tetrahydrofuran-3-yl)methoxy)benzenesulfonamide (CAS 1340414-05-2), molecular formula C11H14ClNO4S and molecular weight 291.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Chloro-2-((tetrahydrofuran-3-yl)methoxy)benzenesulfonamide (C11H14ClNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 5-Chloro-2-((tetrahydrofuran-3-yl)methoxy)benzenesulfonamide 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.
