N-(4-Methoxyphenyl)benzenesulfonamide CAS 7471-26-3

Description

Compared with other compounds in its class, the molecular weight of 263.31 g/mol gives N-(4-Methoxyphenyl)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(4-Methoxyphenyl)benzenesulfonamide (CAS 7471-26-3), molecular formula C13H13NO3S and molecular weight 263.31 g/mol, is a CATO reference standard with documented purity and traceability.

N-(4-Methoxyphenyl)benzenesulfonamide (C13H13NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), N-(4-Methoxyphenyl)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.
